Question

A 5% solution means that : a) 5 g. Sugar is dissolved in 95 g. of water. b) 5 g. Sugar is dissolved in 100 g. Of water.

I want both the answer

Answer 1

Answer:

A 5% solution means that 5g of sugar is dissolved in 95g of water.

Explanation:

This is because here, 5g is the mass of solute and 95g is the mass of solvent.

Mass of solution is the sum of these two masses...hence, mass of solution becomes 100g. And to find % concentration of a solution, the mass of solute is divided by the mass of solution and then multiplied by hundred. So, the mass of solute is 5g and that of solution is 100g. Therefore the % by mass concentration is 5%.

Hope it helped:-)
