Answer:
The volume of the gas will be 573.52 mL.
Explanation:
Boyle’s law states that <u>the pressure of a fixed amount of gas at a constant temperature is inversely proportional to the volume of the gas</u>.
The equation for Boyle's law is:
P₁V₁ = P₂V₂
We want to know V₂, that is, the volume of the container after the compression. We rearrange the equation and calculate:
V₂ = P₁V₁ ÷ P₂
V₂ = 1.14 atm × 815 mL ÷ 1.62 atm = 573.52 mL

Answer:
44.63g
Explanation:
First, let us calculate the number of mole of KBr in 1.50M KBr solution.
This is illustrated below:
Data obtained from the question include:
Volume of solution = 250mL = 250/1000 = 0.25L
Molarity of solution = 1.50M
Mole of solute (KBr) =.?
Molarity is simply mole of solute per unit litre of solution
Molarity = mole /Volume
Mole = Molarity x Volume
Mole of solute (KBr) = 1.50 x 0.25
Mole of solute (KBr) = 0.375 mole
Now, we calculate the mass of KBr needed to make the solution as follow:
Molar Mass of KBr = 39 + 80 = 119g/mol
Mole of KBr = 0.375 mole
Mass of KBr =?
Mass = number of mole x molar Mass
Mass of KBr = 0.375 x 119
Mass of KBr = 44.63g
Therefore, 44.63g of KBr is needed to make 250.0mL of 1.50 M potassium bromide (KBr) solution
