Answer: 1618.8g of Zinc
Explanation:
We begin by writing a balanced chemical equation for the reaction.
Zn (s) + H2SO4 (aq) ----------> ZnSO4 (aq) + H2 (g)
Atomic mass of Zinc is 65.4g/mol
Molecular mass of hydrogen gas is 2.02 g/mol
Looking at the balanced equation;
2.02g is produced by 65.4g of Zn
50g would be produced by 65.4÷ 2.02 x 50 = 1618.8g of Zinc
Answer:
1621.53 g Zn.
Explanation:
The balanced equation is:
Zn + H2SO4 ---> ZnSO4 + H2.
So, using the molar masses of Zn and H2:
65.38 g of Zn produces 2*1.008 = 2.016 g H2.
Thus 2.016 g of H2 is produced from 65.38 g Zn.
and 50g H2 is produced from (50 * 65.38) / 2.016 g
= 1621.53 g Zn.
