<h3>Answer:</h3>
40 atm
<h3>Explanation:</h3>- According to Boyle's law, the pressure and the volume of a fixed mass of a gas are inversely proportional at constant absolute temperature.
- That is;
- At varying pressure and volume,
P1V1 =P2V2
In this case,
Initial volume, V1 = 2 L
Initial pressure, P1 = 1 atm
New volume, V2 = 0.05 L
We are required to calculate the new pressure,
Rearranging the formula;
P2 = P1V1 ÷ V2
= (1 atm × 2L) ÷ 0.05 L
= 40 atm
Therefore, the pressure required is 40 atm
<u>Answer:</u> The volume of isopropyl alcohol present is 254.4 mL and the volume of water present is 540.6 mL
<u>Explanation:</u>
We are given:
32.0 % (v/v) alcohol solution
This means that 32 mL of isopropyl alcohol is present in 100 mL of solution
Volume of water = 100 - 32 = 68 mL
Volume of solution given = 795 mL
Applying unitary method:
In 100 mL of solution, the volume of isopropyl alcohol present is 32 mL
So, in 795 mL of solution, the volume of isopropyl alcohol present will be =
Volume of water in given amount of solution = 795 - 254.4 = 540.6 mL
Hence, the volume of isopropyl alcohol present is 254.4 mL and the volume of water present is 540.6 mL
