Question bank/JEE Main/Chemistry

A bottle of H_3PO_4 solution contains 70 acid by mass. If the
density of the solution is 1.54 g cm^-3, the volume of the H_3PO_4
solution required to prepare 1 L of 1 M solution is

A91mLB45mLC30mLD23mL

Show answer and solution▾

70 W/W H_3PO_4
70g H_3PO_4 in 100g / cm^3
P = 1.5 g/ cm^3 M = $\frac{70}{98} \times \frac{1000}{100}$ × 1.54 = 11
11 × V = 1 × 1000
V = 90.9[IMAGE] 91
