Answer:
v₂ = 39L
Explanation:
Given parameters:
Initial volume of gas = 20L
Initial temperature = 140K
Unknown:
Final volume = ?
Solution:
Since the standard temperature of any gas is 273K, the final temperature is this 273K;
Applying Charles's law:
= 
v and T are volume and Temperature
= 
v₂ x 140 = 20 x 273
v₂ = 39L
Answer:
23.8
Explanation:
Formula
weight % = weight of solute/ weight of solution x 100
weight of solution = weight of salt + weight of water
weight of solution = 1.62 lb + 5.20 lb = 6.82 lb
weight % = 1.62 / 6,82 x 100
weight % = 0.238 x 100
weight % = 23.8
