(Note: Atomic masses, in daltons are approximately 12 for carbon, 1 for hydrogen, and 16 for Oxygen)
Which is it?
a.) 10 grams
b.) .1 grams
c.) 6 grams
d.) 60 grams
e.) .6 grams

The answer should be 60g.
The Mr of C2H4O2= 2(12) + 4(1) + 2(16)
= 60
Since 1mol = 60g,
0.1mol = 6g
However, this is only for 1dm^3= 1L
So for 10L (10dm^3),
the mass= 6g x 10
= 60g

the molar mass of C2H4O2 is 2*12+4*1+2*16=60
1L of 0.1m contains 0.1*60 =6g
and 10L contains 6*10 = 60g of C2H4O2

M=wt\gmw *1\V
0.1=WT\60 *1\10
wt=60 gr
