Question

If a bottle of concentrated hydrochloric acid contains a density of 36% by weight and a specific weight of 1.18, what is its standard of acid?

Answer 1

Weight of 1 litre of acid solution$=1.18×1000$

$=1180g$

Mass of acid$=\frac{36}{100}×1180=424.8g$

Concentration$=\frac{424.8}{36.5}=11.64M$
