Question

calculate the concentration of aqueous solution of glucose obtained by dissolving 10gm of glucose in 1000 of water​

Answer 1

Explanation:

$concentration \: of \: glucose \\ \\ = \frac{mass \: of \: solute}{mass \: of \: solution}$

$mass \: of \: glucose = 10gm \\ \\ mass \: of \: solution = \\1000 + 10 = 1010gm$

$concentration = \frac{10}{1010} \times 100\\ \\= \frac{100}{101} \% = 0.99\%$
