A ridged 1.0L cylinder contains 1.0 moles of O2, gas at 25.0°C and another ridged 1.0 L cylinder contains 1.0 moles of CH4. gas at 25.0°C. Is the average speed of the O2 gas particles greater than, less than, or the same as the average speed of the CH4 gas particles? Justify your 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
