Question

If you have 72.5 g of carbon that can be converted to acetylene, what mass of hydrogen will be needed for the conversion? answer the full questioun

Answer 1

2C+H2-->C2H2
24g of C gives 26g of C2H2
72.5g of C gives x g of C2H2
x=26*72.5/24=78.54
then 2g of H2 gives 26g of C2H2
y g of H2 gives 78.5g of C2H2
y=2*78.5/26=6.041
so the H2 required is 6.041 g
I think I might be right
