60 is the answe for the last, dm3 can’t be 60,000. You have to divide by 1000

I was worried I got the sixth marker wrong, but I also got 60 000 dm^3, is it definitely right?

I also got 60000 but some people in my year said it was 60 so I am not sure now. What did everyone get for the aluminium one???

Isn't it you multiply the Moles by 24dm3 so the answer 60,000 was in dm^3, not cm3 so you did not have to convert?

it is 60000 you wouldn't divide by 1000 anyway since the unit was dm^3
