A sample of (N2H5)2C3H4O4 contains 1.084 x 1024 carbon atoms. How many moles of hydrogen atoms are there in the same sample? Avogadro’s number = 6.022 x 1023.
I believe Bob P counted the H atoms wrong. It's 10 from the (N2H5)2 and 4 more from the other part of the formula for a total of 14 and not 22.
Well, let's start by figuring out how many moles of carbon atoms we have. Given that we have 1.084 x 10^24 carbon atoms, and Avogadro's number is 6.022 x 10^23, we can divide the number of carbon atoms by Avogadro's number to get the number of moles.
So, 1.084 x 10^24 carbon atoms / 6.022 x 10^23 = almost 1.8 moles of carbon.
Now, we need to see the ratio of hydrogen atoms to carbon atoms in the compound (N2H5)2C3H4O4.
As we can see, there are 4 carbon atoms in the compound, but they are not all the same. So, we need to look at each carbon atom and the corresponding number of hydrogen atoms attached to it.
Let's take the first carbon atom, which is part of the (N2H5)2 part. This carbon atom has 3 hydrogen atoms attached to it.
Now let's look at the other three carbon atoms (in the C3H4O4 part). These atoms have 1, 2, and 4 hydrogen atoms attached respectively.
So, in total, we have 3 hydrogen atoms for the first carbon atom, 1 hydrogen atom for the second carbon atom, 2 hydrogen atoms for the third carbon atom, and 4 hydrogen atoms for the fourth carbon atom.
Adding all those up, we have 3 + 1 + 2 + 4 = 10 moles of hydrogen in the sample.
So, the answer is 10 moles of hydrogen atoms.
To find the number of moles of hydrogen atoms in the sample, we first need to determine the number of (N2H5)2C3H4O4 molecules in the sample.
Given that there are 1.084 x 10^24 carbon atoms in the sample, and each (N2H5)2C3H4O4 molecule contains 4 carbon atoms, we can calculate the number of (N2H5)2C3H4O4 molecules as follows:
Number of (N2H5)2C3H4O4 molecules = (1.084 x 10^24 carbon atoms) / (4 carbon atoms per molecule)
Next, we know that each (N2H5)2C3H4O4 molecule contains 4 hydrogen atoms. Therefore, the total number of hydrogen atoms in the sample can be determined by multiplying the number of (N2H5)2C3H4O4 molecules by the number of hydrogen atoms per molecule:
Number of hydrogen atoms = (Number of (N2H5)2C3H4O4 molecules) x (4 hydrogen atoms per molecule)
Finally, to convert the number of hydrogen atoms to moles, we divide by Avogadro's number (6.022 x 10^23):
Number of moles of hydrogen atoms = (Number of hydrogen atoms) / Avogadro's number
By following these steps, we can find the number of moles of hydrogen atoms in the given sample.
To find the number of moles of hydrogen atoms in the sample, we first need to determine the number of hydrogen atoms present in the compound (N2H5)2C3H4O4.
The formula shows that there are 5 hydrogen atoms in one N2H5 group and 4 hydrogen atoms in one C3H4O4 group.
Number of hydrogen atoms in N2H5 = 5
Number of hydrogen atoms in C3H4O4 = 4
The compound (N2H5)2C3H4O4 contains two N2H5 groups and one C3H4O4 group.
Number of hydrogen atoms in (N2H5)2C3H4O4 = 2 * (Number of hydrogen atoms in N2H5) + Number of hydrogen atoms in C3H4O4
Number of hydrogen atoms in (N2H5)2C3H4O4 = 2 * 5 + 4 = 14
Therefore, the sample contains 14 hydrogen atoms.
Now, to calculate the number of moles of hydrogen atoms, we can use Avogadro's number.
Number of moles of hydrogen atoms = Number of hydrogen atoms / Avogadro's number
Number of moles of hydrogen atoms = 14 / (6.022 x 10^23) = 2.321 x 10^-23 moles
Hence, there are approximately 2.321 x 10^-23 moles of hydrogen atoms in the given sample.
counting 10 H + 12h=22H
so it must be 22* 1.084E24/avanumber
