Question

how many litres of 15 percent sugar solution would it take to get 75 gm of sugar​

Answer 1

Let the value be x

15% of (75+x)=75

15/100 of 75+x=75

15(75+x)/100=75

3(75+x)/20=75

3(75+x)=75×20

75+x=75×20/3

75+x=25×20

75+x=500

x=500-75

therefore,

x= 425

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 = 100/15×75=500mL of solution

Converting this into liters, we use the conversion factor:

1 L = 1000 mL

So, 1l\ 1000 ml ×500mL=0.5L

Hence, the volume required is 0.5 L.
