If 133mL of a 1.2 M glucose solution is diluted to 41.0L, what is the molarity of the diluted solution?
WITCHER [35]

the formula we is as follows:-

M1V1= M2V2

where

M1=1.2

V1=0.133l

V2=41l

M2=?

1.2 × 0.133 = 41 × M2

0.1596 = 41 × M2

M2 = 0.15960/41

M2 = 0.0038926829

Naddika [18.5K]
<h3><u>Answer;</u></h3>

A gas in a liquid

<h3><u>Explanation;</u></h3>
  • Pressure affects the solubility of gases. According to Henry's law, the solubility of a gas in a liquid is proportional to the partial pressure of the gas above the liquid at a given temperature,
  • Therefore; For the solubility of gases in liquids, as pressure increases, solubility increases. Hence pressure will have a effect on a solution with a gas in liquid.
