Question

Which of the following solutions would always contain 10.0 g of solute per 90.0 g of solvent?

Group of answer choices

11.1% (m/m) solution

11.1% (v/v) solution

10.0% (m/v) solution

10.0% (m/m) solution

Answer 1

Here last option is correct

10.0 (m/m) solution

Explanation is given in below picture.

A solution contains log of solute and ro og of solvent Total mass of solution = loog O Moss series solute = 109 Mos poranty of solute - to y = 10% mlen Hence 10.0% (m/m) solution will always contain solute per 90.0g of solvert. Wrong options for 11.1% (m/m) solution loog Solotron will contaan inng of solute por 98.9 grams of solvent Jor 11.19% (v/v) solution 100 ml solution will contain aliml of solute per 88.9 ml of solvert Here we cannot tell about mas elas both solote and solvent may have different density. For 10.0% (mv) solution The 100 ml solotron will contan og of solute here we cannot tell about mass of solvent present in 200ml solution CScanned with CamScanner
