Determine the m/v% of a solution where 5 g of sugar is dissolved in enough water

2 %m/v

Explanation:

Step 1: Given data

Step 2: Calculate the %m/v of sugar in the solution

We will use the following expression.

%m/v = mass of sugar/volume of solution × 100%

%m/v = 5 g/250 mL × 100% = 2 %m/v

This means that there are 2 grams of sugar every 100 milliliters of solution.

Option B. 101.60 KPa

Explanation:

From the question given above, the following data were obtained:

Total pressure (Pₜ) = 105.00 KPa

Partial pressure of wet gas (Pᵥᵥ) at 26 °C = 3.4 KPa

Partial pressure of dry gas (Pₔ) =?

Total pressure = partial pressure of dry gas + partial pressure of wet gas

Pₜ = Pₔ + Pᵥᵥ

105 = Pₔ + 3.4

Collect like terms

105 – 3.4 = Pₔ

Pₔ = 101.60 KPa

Therefore, the partial pressure of the dry gas is 101.60 KPa
