Calculate the following:

(a) mass of water in the hydrate sample (g):
(b) number of moles of water in the sample:
(c) mass of pure salt in the sample (g):
(d) number of moles of salt in the sample:
(e) molar ratio of water to salt in the sample:

If the mass of the empty crucible (g): 53.200 and the mass of the crucible and hydrate (g): 58.200 and the mass of the crucible and pure salt (g): 56.396

I must guess what you did since you didn't post it. I assume

56.396 = mass xble + salt
-53.200 = mass empty xble
--------------
3.196 g = mass salt

58.200 = mass xble + hydrate
-53.200 = mass empty xble
---------
5.000 g = mass hydrate

5.000 = mass hydrate
-3.196 = mass salt
---------
1.804 g = mass water added to salt.
a) 1.804 g
b) moles = grams/molar mass
c) see above
d) It would have helped if you had given a little more information like what you were doing and the name of the salt. moles salt = grams/molar mass
e) Not enough information provided. You want to find the ratio of moles salt (d) to moles H2O(b)

Thank you I been trying to really get the first three I think I figured out the rest through your help thanks.

To calculate the values, we need to use the given masses of the empty crucible, the crucible and hydrate, and the crucible and pure salt. Let's proceed step by step:

Step 1: Calculate the mass of water in the hydrate sample (g):
Mass of hydrate = Mass of crucible and hydrate - Mass of empty crucible
Mass of hydrate = 58.200 g - 53.200 g = 5.000 g

Step 2: Calculate the number of moles of water in the sample:
Number of moles of water = Mass of water / Molar mass of water
Molar mass of water (H2O) = 2 g/mol (for hydrogen) + 16 g/mol (for oxygen) = 18 g/mol

Number of moles of water = 5.000 g / 18 g/mol ≈ 0.2778 mol

Step 3: Calculate the mass of pure salt in the sample (g):
Mass of salt = Mass of crucible and pure salt - Mass of empty crucible
Mass of salt = 56.396 g - 53.200 g = 3.196 g

Step 4: Calculate the number of moles of salt in the sample:
Number of moles of salt = Mass of salt / Molar mass of salt

Here, we need to know the molar mass of the salt, so we'll need more information to proceed. Could you provide the name or formula of the salt in the sample?

Step 5: Calculate the molar ratio of water to salt in the sample:
Molar ratio of water to salt = Number of moles of water / Number of moles of salt

Similarly, without information about the salt, we are unable to calculate the molar ratio accurately. If you provide the salt's name or formula, we can assist you further.

To calculate the values mentioned, we will need to use the given information and apply some stoichiometry calculations.

Let's start with the first part:

(a) Mass of water in the hydrate sample (g):
To find the mass of water, we can subtract the mass of the empty crucible from the mass of the crucible and hydrate.

Mass of water = Mass of crucible and hydrate - Mass of empty crucible
Mass of water = 58.200 g - 53.200 g
Mass of water = 5.000 g

Therefore, the mass of water in the hydrate sample is 5.000 grams.

Now let's move on to the second part:

(b) Number of moles of water in the sample:
To find the number of moles of water, we need to use the molar mass of water, which is 18.015 g/mol.

Number of moles of water = Mass of water / Molar mass of water
Number of moles of water = 5.000 g / 18.015 g/mol
Number of moles of water ≈ 0.2778 mol

So, the number of moles of water in the sample is approximately 0.2778 moles.

Moving on to the third part:

(c) Mass of pure salt in the sample (g):
To find the mass of pure salt, we can subtract the mass of the empty crucible from the mass of the crucible and pure salt.

Mass of pure salt = Mass of crucible and pure salt - Mass of empty crucible
Mass of pure salt = 56.396 g - 53.200 g
Mass of pure salt = 3.196 g

Therefore, the mass of pure salt in the sample is 3.196 grams.

Now let's continue to the fourth part:

(d) Number of moles of salt in the sample:
To find the number of moles of salt, we need to use the molar mass of the salt.

Unfortunately, we don't have information about the identity of the salt. If you know the formula or molar mass of the salt, please provide it so we can proceed with the calculation.

Finally, the last part:

(e) Molar ratio of water to salt in the sample:
To determine the molar ratio of water to salt, we can use the moles of water and moles of salt once we have the latter.

However, without the molar mass or formula of the salt, we cannot calculate the molar ratio at this point.

Please provide the molar mass or formula of the salt to complete the remaining calculations.
