People with diabetes have to monitor and restrict their sugar intake. What volume of apple juice could a diabetic person drink, if the person's sugar allowance for that beverage was 8.0 g? Assume that the
apple juice has a sugar concentration of 8.0 % w/v.

The volume of apple juice could  a diabetic person drink : 100 ml

Given

sugar allowance = 8 g

sugar concentration of apple juice : 8.0% w/v

Required

Volume of apple juice

Solution

The concentration of a substance can be expressed in several quantities The concentration shows the amount of solute in a unit of the amount of solvent.

% w/v = mass of solute (weight) in g / 100 ml solution

So for 8% w/v = 8 g of sugar(solute) in 100 ml of apple juice
