Answer:
I don't know if this is right but..
Explanation:
It is important to keep the volume of the reactant constant because it ensures that the temperature change was the result of the reactants consumed
The molecular formula for mustard gas is C₄H₈SCl₂
the molecular mass of mustard gas - 159.09 g/mol
atomic mass of H is 1 g/mol
The mass of H in 1 mol of compound - 1 x 8 = 8 g
this means that in 159.09 g of compound , 8 g of H present
mass percentage of hydrogen = 8 g/ 159.09 g x 100%
mass percentage of hydrogen = 5.03%
89.1% Au
The molar mass of Au2O3 is 2(196.97) + 3(16.00) = 441.94 g/mol
The mass percent of Au is therefore 2(196.97) / 441.94, which is 393.94/441.94 = 0.891 —> 89.1%
