Answer to Question #99211 in General Chemistry for Chukwuemeka

Question

A solution of glucose contain 0.45g of glucose in 95cm³ of solution
a) what is the concentration of the glucose solution in g/dm³
b) what is the mass of glucose dissolved in 250cm³ of the glucose solution

Answer 1

a)

$$W_{glucose} = {m_{glucose} \over V_{solution}} = {0.450g \over 0.095dm^3} = 4.737 g/dm^3 \approx 4.74 g/dm^3$$

b)

$$m_{glucose} = W_{glucose}*V_{solution} = 4.737 g/dm^3 * 0.250dm^3 = 1.184 g \approx 1.18 g$$
