Answer 2

Given:

A. 100 grams rice grains and 200mL water

B. 375mL and 20grams sugar

To find:

Solute:

Solution:

computation:

Final answer:

Solution:

From given, we have the data as follows.

A. 100 grams rice grains and 200mL water

B. 375mL and 20grams sugar

The formula used is, c% = solute/solution × 100%

A. 100 grams rice grains and 200mL water

Solute: rice

Solvent: water

composition: c% = solute/solution × 100%

c% = rice/water × 100%

c% = 100 g/200 mL × 100%

c% = (100 × 0.001) L/200 mL × 100%

c% = 0.05

Final answer: 0.05%  

B. 375mL water and 20grams sugar

Solute: sugar

Solvent: water

composition: c% = solute/solution × 100%

c% = sugar/water × 100%

c% = 20 g/375 mL × 100%

c% = (20 × 0.001) L/375 mL × 100%

c% = 5.33 × 10^{-3}

Final answer: 5.33 × 10^{-3} %  

A. 0.05%

B. 5.33 × 10^{-3} %
