Question
when 2g of a gas A is introduced into an evacuated flask kept at
25 centigrade, the pressure is found to be 1 atmosphere.if 3g of another gas is then added to the same flask, the total pressure becomes 1.5atm. assuming ideal behaviour, the ratio of their molecular weights is

Answers
call the 2nd gas B
3 g of B is half as many moles as 2 g of A
B / A = 3 / 1
3 g of B is half as many moles as 2 g of A
B / A = 3 / 1
