Answer:
The volume of the balloon would be 374 L.
Explanation:
Initially, He occuplies a volume of 17.0 L (V₁) at a pressure of 22.0 atm (P₁). If pressure decreases to 1.00 atm (P₂), volume is expected to increase. Assuming ideal behavior of the gas and constant temperature, we can calculate the final volume (V₂) using Boyle's Law.
The mass of 63 ml sample : 79.38 g
<h3>Further explanation</h3>Given
20 ml and 25.2 g of glycerol
Required
The mass of 63 ml sample
Solution
Density is the ratio of mass per unit volume
Density formula:
Density of glycerol :
= m : V
= 25.2 g : 20 ml
= 1.26 g/ml
Mass of 63 ml sample :
= density x volume
= 1.26 g/ml x 63 ml
= 79.38 g
