Question

How many grams of chlorine are required to completely react with 0.40g of hydrogen to yield HCL? Also calculate the amount of HCL formed.

Answer 1

0.4g H2=0.4mol
H2+Cl2>2HCl
Mol.no of Cl2 equal 2x 35.5gmol-1
So grams of Cl2=0.4x(molar mass of Cl2)
amount of HCl:
Mol ratio H2:HCl equal 1:2
So amount of HCL=H2x2(in mole)!
Then mass of hcl=molar mass of hcl x mol no. mentioned above
U can find the molar mass of those gases according to periodic table
