Question

How do you prepare 500ml of 1.77M H2SO4 solution from an 18.0M H2SO4 Stock solution

Answer 1

Answer:

Take 49.2-ml of 18.0 M H2SO4 stock solution and pour it into a 500-ml volumetric flask. Fill to the 500-ml line with distilled water to make 1.77M H2SO4 solution.

Explanation:

use the formula M1V1=M2V2

volume must be in liters(L)

$(1.77)(500 \times {10}^{ - 3} ) = (18)v2 \\ 0.885 = 18v2 \\ v2 = \frac{0.885}{18} \\ v2 = 0.04916$

0.04916L × 1000 = 49.16 ml = 49.2 ml
