Answer 2

Answer:

a 3/4

Explanation:

Pa= 1.5 Pb

Pb = 2 Pb

According to the ideal gas equation we have pressure,p =pRT/M , where M is the molecular weight of the ideal gas

such that p/p = pRT/M

therefore M = pRT/p

where R and T are constant

so,M is proportional to p/p

Ma/Mb = Pa/Pb × Pb/Pa = 1.5 ×1/2 =0.75 = 3/4
