How many moles of H atoms are there in 33.4282 grams of C2H4Cl2?
How many moles C2H4Cl2 do you have? moles = grams/molar mass. Then moles H atoms will be 4 times that.
Thank you Dr. Bob.
To determine the number of moles of H atoms in a given compound, we first need to calculate the molar mass of the compound.
The molar mass of C2H4Cl2 can be calculated by summing up the atomic masses of its constituent atoms.
The atomic masses are:
C (Carbon) = 12.01 g/mol
H (Hydrogen) = 1.01 g/mol
Cl (Chlorine) = 35.45 g/mol
So, the molar mass of C2H4Cl2 is:
(2 * 12.01 g/mol) + (4 * 1.01 g/mol) + (2 * 35.45 g/mol) = 98.96 g/mol
Now, we can use the molar mass to convert the grams of C2H4Cl2 to moles.
Given: Mass of C2H4Cl2 = 33.4282 grams
To find the number of moles, we use the formula:
Number of moles = Mass / Molar mass
So, Number of moles = 33.4282 g / 98.96 g/mol
Calculating this value will give you the answer - the number of moles of H atoms in 33.4282 grams of C2H4Cl2.
