9.60g of a gas X occupies the same volume at 0.30g of hydrogen under the same condition calculate the molar of X (H=1)?
H=1
1×9.6÷0.3
the volume is by moles
convert the H to moles (remember, its diatomic in the gas phase ... H2)
that many moles of X has the given mass
To calculate the molar mass of gas X, we can use the formula:
Molar Mass = (Mass of gas X) / (Number of moles of gas X)
First, we need to find the number of moles of hydrogen:
Moles of hydrogen = (Mass of hydrogen) / (Molar mass of hydrogen)
= 0.30g / 1g/mol
= 0.30 moles
Now, we can calculate the molar mass of gas X:
Molar mass of X = (Mass of gas X) / (Number of moles of gas X)
= 9.60g / 0.30 moles
≈ 32g/mol
Therefore, the molar mass of gas X is approximately 32g/mol.
To calculate the molar mass of gas X, we can use the concept of molar mass and the given information.
Molar mass is the mass of one mole of a substance, represented in grams per mole (g/mol). It is equal to the atomic mass of the element or the sum of the atomic masses of all the elements in a compound.
First, we need to calculate the number of moles of hydrogen (H2) using the given mass of hydrogen (0.30g) and its molar mass.
The molar mass of hydrogen (H) is 1 g/mol because it is given that H has an atomic mass of 1.
Number of moles of hydrogen (H2) = given mass / molar mass
Number of moles of hydrogen (H2) = 0.30g / (2g/mol)
Next, we need to determine the number of moles of X by using the concept of the ideal gas law.
According to the ideal gas law, PV = nRT, where P is pressure, V is volume, n is the number of moles, R is the ideal gas constant, and T is temperature. Since the volume and conditions are the same for both gases, we can equate the number of moles of X to the number of moles of hydrogen.
Number of moles of X = Number of moles of hydrogen (H2)
Finally, we can use the concept of molar mass to calculate the molar mass of gas X.
Molar mass of X = Mass of X / Number of moles of X
Molar mass of X = 9.60g / Number of moles of hydrogen (H2)
By substituting the value of the number of moles of hydrogen (H2) from the previous step, we get:
Molar mass of X = 9.60g / (0.30g / (2g/mol))
Simplifying further:
Molar mass of X = 9.60g / 0.15 mol
Molar mass of X = 64 g/mol
Therefore, the molar mass of gas X is 64 g/mol.
