• # question_answer 80) Calculate the mass of anhydrous HCl in 10 ml of concentrated HCl $\left( d=1.2\text{ }g/ml \right)$ solution having $37%$ HCl by weight. A) 4.44 g              B) 4.44 mgC) $4.44\,\,\times \,\,{{10}^{-3}}\,g$        D) $0.444\text{ }\mu g$

$\because$ 37 gm HCl in 100 gm solution volume of solution $=\,\,\frac{100}{1.2}\,\,=\,\,83.33\,\,ml$ $\therefore$ 10 ml solution contains $=\,\,\frac{37}{83.33}\,\,\times \,10\,ml$ $=\text{ }4.44\,gm$
