Question

26 percent weight by weight of ammonia solution and density 0.85 gram per ml the molarity

Answer 1

$molarity \: = \frac{10 \times d \times x}{gmw} \: where \: x = mass \: percentge$

$\: \: \: \: \: \: \: \: = \frac{10 \times 0.85 \times 26}{17}$

$= \frac{85 \times 2.6}{17}$

$= 5 \times 2.6$

$= 13$
