HELP ME PLEASE I NEED IT LIKE RN, (WILL OFFER BRAINLIEST) A mixture of helium (He) and methane (CH4) is placed in an effusion apparatus.

V1/V2 = √m2/√m1

1. What is the molar mass of He? (round to the nearest hundredths)

2. What is the molar mass of CH4 (round to the nearest hundredths)

3. What is the ratio of the effusion rate of the helium to methane (Round to hundredths)

ok

Explanation:

1. 4.00

2. 16.04246

I'm not sure about 3.
