Question

How many litres of 15% ( mass / volume ) sugar solution would it take to get 75g of sugar?

Answer 1

Hello

HERE IS THE ANSWER ..

_______________

let the no. of litres of water be x

Therefore the solution=75+x

15% (75+x)=75

75+x=75*100/15

x=500-75

x=425 litres.

Hope it helps to you.

Answer 2

Answer: The volume required is 0.5 L

Explanation:

We are given:

15 % (m/v) sugar solution.

This means that 15 g of sugar is present in 100 mL of solution

To calculate the volume required, we apply unitary method:

If 15 gram is present in q00 g of solution.

Then, 75 gram of sugar will be present in = $\frac{100}{15}\times 75=500mL$ of solution

Converting this into liters, we use the conversion factor:

1 L = 1000 mL

So, $\frac{1L}{1000mL}\times 500mL=0.5L$

Hence, the volume required is 0.5 L
