Question

50g of caco3will react with _____gram of 20% HCl by weight​

Answer 1

Answer:

3

Explanation:

Answer 2

Explanation:

caco³ +2hcl gives cacl²+co²+h²o

1mol 2mol

20%hcl contains 20g hcl in 100g water

1mol caco³ = 100g

50g caco³ =0.5 moles caco³

0.5 moles caco³ correspond to 1mol hcl

1mol hcl =36.5ghcl

20ghcl in 100g water

36.5ghcl =182.5g H²O

hence, 182.5g solution of 20 hcl is required
