the pressure on 2.50L of N20 changes from 105 kPa to 40.5 kPa. if the temperature does not change, what will the new volume be.
tresset_1 [31]

Answer:

6.48L

Explanation:

Given parameters:

V₁ = 2.5L

P₁  = 105 kPa

P₂  =  40.5 kPa

Condition: constant temperature

Unknown:

V₂  = ?

Solution:

To solve this problem, we are considering pressure and volume relationship. This should be solved by applying the knowledge of Boyle's law.

The law states that "The volume of fixed mass of a gas varies inversely as the pressure changes if the temperature is constant".

Mathematically;

                     P₁V₁  = P₂V₂

where P and V are pressure and volume, 1 and 2 represents initial and final states.

Substitute to find the V₂;

                  105 x 2.5  = 40.5 x  V₂

        Solving for V₂ gives 6.48L

A solution was made by mixing 60.5 g of glucose (C6H12O6) with enough water to make 325 ml of solution. What is the percent (mas
IgorC [24]

mass percent concentration = 15.7 %

molar concentration of glucose solution 1.03 M

Explanation:

To calculate the mass percent concentration of the solution we use the following formula:

concentration = (solute mass / solution mass) × 100

solute mass = 60.5 g

solution mass = solute mass + water mass

solution mass = 60.5 + 325 = 385.5 g (I used the assumption that the solution have a density of 1 g/mL)

concentration = (60.5 / 385.5) × 100 = 15.7 %

Now to calculate the molar concentration (molarity) of the solution we use the following formula:

molar concentration = number of moles / volume (L)

number of moles = mass / molecular weight

number of moles of glucose = 60.5 / 180 = 0.336 moles

molar concentration of glucose solution = 0.336 / 0.325 = 1.03 M
