Which of the following statements is/are correct

A

`196.0 g` of pure `H_(2) SO_(4)` is required for the production of `365.0 g` of conc `HCl` containing 40% `HCl` by weight.

B

`245.0 g` of 80% `H_(2)SO_(4)` by weight is required for the production of `365.0 g` conc. `HCl` containing 40% `HCl` be weight

C

2 mol of pure `H_(2)SO_(4)` is required for the production of `365 g` of 40% `HCl`

D

2.5 mol of 80% `H_(2)SO_(4)` is required for the production of `36.5g` of 40% HCl`.

Text Solution

Verified by Experts

The correct Answer is:
A, B, C, D
a. Weight of `40 % HCl -= (40)/(100) xx 36.5 = 146 g`
2 mol `HCl (2 xx 36.5 = 73) -= 1 "mol" H_(2) SO_(4) (98 g)`
Weight of `H_(2) SO_(4) = (146 g HCl) ((98 g H_(2) SO_(4))/(73 g Cl))`
`= 196 g H_(2) SO_(4)`
b. Weight of 80% `H_(2) SO_(4)`
` = (196 xx 100)/(80) = 245 g H_(2) SO_(4)`
c. Mole of pure `H_(2) SO_(4)`
`= (196)/(98) = 2 "mol" H_(2) SO_(4)`
d. Mole of `80% H_(2) SO_(4) = (245)/(98) = 2.5 "mol" H_(2) SO_(4)`
