At 25 °c and 795 torr, carbon dioxide has a solubility of 0.0356 in water. what is its solubility at 25 °c and 1590 torr

C₂ = 0.0712

Explanation:

Given data:

Pressure 1 = 795 torr

Solubility = 0.0356

Pressure 2 = 1590 torr

Solubility = ?

Solution;

Pressure and solubility are both directly proportional to each other.

P₁/C₁ = P₂/C₂

795 /0.0356  = 1590 / C₂

C₂ = 1590 × 0.0356 / 795

C₂ = 56.604 /795

C₂ = 0.0712

a. the law of proportion states the combination of 2 atoms in a specific ratio to produce multiple compounds such as the given statement of question ‘1st compound contains 88.8 % cu ’ indicates 88.8 g of cu is present along with 11.2 g oxygen in 100 g of compound whereas the statement ‘2st compound contains 79.9 % cu ’ indicates 79.9 g of cu is present along with 20.1 g oxygen in 100 g of compound

1st compound contains 88.8 g cu

for cu

m = 63 g /mol

atomic % = 88.8 /63 = 1.42

for o

m = 16 g /mol

atomic % = 11.2 /16 = 0.7

b. the emperical formula of 1st compound is

cu1.4o0.7
