Question

Q4.A solution contains 30 g of glucose, 20 g of salt in 500 mL of water. Calculate
the mass percent of
(a) glucose,
(b) salt (density of water = 1 g/mL).​

Answer 1

Explanation:

The solution contain 30 glucose,20 g salt in 500ml of water (density of water = 1 g/ml so 500ml/500 g)

The solution contain 30 glucose,20 g salt in 500ml of water (density of water = 1 g/ml so 500ml/500 g)Total weight of solution by mass = 30 g + 20 g + 500 g = 550 g

The solution contain 30 glucose,20 g salt in 500ml of water (density of water = 1 g/ml so 500ml/500 g)Total weight of solution by mass = 30 g + 20 g + 500 g = 550 gMass % of salt = 20/550*100 = 3.63 %

The solution contain 30 glucose,20 g salt in 500ml of water (density of water = 1 g/ml so 500ml/500 g)Total weight of solution by mass = 30 g + 20 g + 500 g = 550 gMass % of salt = 20/550*100 = 3.63 %mass % of glucose = 30/550*100 = 5.45 %

The solution contain 30 glucose,20 g salt in 500ml of water (density of water = 1 g/ml so 500ml/500 g)Total weight of solution by mass = 30 g + 20 g + 500 g = 550 gMass % of salt = 20/550*100 = 3.63 %mass % of glucose = 30/550*100 = 5.45 %Hope it's help you
