What is the mass of 2 moles of ethane? I have an answer but I'm not sure.

I got 60g I'm not sure if I'm doing it right but I hope I am!

Here are the other answers if I'm wrong:

A. 60g
B. 36g
C. 30g
D. 18g

Thanks xxx

Ethane's molecular mass is 30g (2x12 + 6x1) so one mole's mass is 30g.
Multiply this by two to get the answer for two moles -> 60g
So yep, you're absolutely right, well done :)
Hope I helped :)

Ethane is C2H6, so has a molecular mass of (approximately) 12 + 12 + 1 + 1 + 1 + 1 + 1 + 1, or 30

So one mole of ethane weighs 30 grams...

So TWO moles of ethane would weigh 60 grams, and you were either doing it right or you are lucky at guessing!

No, you're right.
