Question

What volume of a saturated solution of X at 0°C would yield 10.0 g of the dry salt if the solubility of Y at 0°C is 5.0 mol/dm³? [X=160]

a) 2.0 dm³
b) 1.0 dm³
c) 0.5 dm³
d) 2.5 dm³

Answer 1

The volume of a saturated solution of X at 0°C that would yield 10.0 g of the dry salt is 0.0625 dm³.

Step-by-step explanation:

To find the volume of a saturated solution of X at 0°C that would yield 10.0 g of the dry salt, we need to use the solubility of Y at 0°C. The solubility of Y is given as 5.0 mol/dm³. We can use the equation:

volume of solution = mass of dry salt / solubility

Plugging in the values, we get:

volume = 10.0 g / (5.0 mol/dm³)

Converting grams to moles:

volume = 10.0 g / (160 g/mol)

volume = 0.0625 mol / (5.0 mol/dm³)

volume = 0.0625 dm³ = 0.0625 dm³
