A submersible balloon I s sent to the bottom of the ocean. On shore, the balloon had a capacity of 162 L when it was filled at 21.0 °C and standard pressure. When it reaches the ocean floor, which is at 5.92 °C, the balloon occupies 18.8 L of space. What is the pressure on the ocean floor?

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

cu2o

it's 3.2 on edge, i just took the test.
