Calculate the volume of c2h2 that is collected over water at 23 ∘c by reaction of 1.53 g of cac2 if the total pressure of the gas is 755 torr . (the vapor pressure of water is 21.07 torr.)

space exploration has led to the development and technological improvement of many everyday items. (if this answer is wrong i will find the right answer) : )

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
