Question

In How many grams of water, 36.5g hcl should be dissolved so that 10% w/w solution will be obtained ​

Answer 1

Explanation:

10 percent weight by weight

weight of solute /weight of solution =10÷100

36.5÷36.5+x=1÷10

365=36.5+x

365-36.5=x

328.5

Answer 2

Answer:

10%w/w solution means 10grams HCl in 90 g of water.

This implies that 1gram of HCl is present in 90/10 =9 grams of water.

This again implies that 36.5 grams of HCl is present in 9 × 36.5 = 328.5 grams of water.

Therefore, 36.5 gram HCl should be added to 328.5 gram water to make 10% w/w solution

Hope it helps.
