Hi, so to solve for this, we need to calculate first the molar mass of oxalic acid.
00:08
So molar mass of c2o4h2 2h2o.
00:19
So the atomic mass of carbon is 12 .01.
00:23
Multiply this by 2 because we have 2 carbons here and then oxygen is 4.
00:28
So that's 16 times 4 plus 2h2.
00:33
So that's 1 .01 times 2.
00:35
Then we have 2h2o.
00:37
So that means we'll just use directly the molar mass of water, which is 18 .02.
00:42
Then multiply this by 2.
00:44
This will give us 126 .08 grams per mole.
00:49
Now to solve for molarity, this is equivalent to the mole of solute over the volume of the solution in terms of liters...
