Before solving for moles of hydrogen produced you must first solve for moles of zinc how do you convert grams of zinc to moles of zinc?

Converting grams to moles of zinc,

; Use the formula...,

moles = (given mass in grams)/relative atomic mass of zinc

Multiply 10 grams of Zn x (1 mol Zn/65.39 g)  

I hope this helps!
