Ask Mr. Kirk
1 mol Zn 65.4g Zn
65.4mol Zn 1g Zn

Zn H2 SO4 ZnSO4 H2
EXCELENT!!!!!!!! What's next
1 mol Zn 65.4g Zn
31.8 1

When zinc reacts with sulfuric acid, as shown
here, what weight of hydrogen is produced from
31.8g of zinc
Zn H2 SO4 ZnSO4 H2
31.8 x 1 mol ZN x 1 65.4
g ZN
1 mol H2 x 1 mol Zn
2g H2 1 mol H2
So what is your answer
.972 g H2
9.72g H2
Pick ur nose
