This chemistry question is worded funnily

What is the molar mass of a substance if 0.300mol has a mass of 40.2g?

I don't get it, but I think it's 12.06?

0.300 x 40.2?

0.300mole has a mass of 40.2g
Therefore 1 mole has a mass 40.2/0.3 = 134
Thus the molar mass is 134.

If 0.3 moles have a mass of 40.2 g then
1.0 mole will have a mass = 1.0 x 40.2 / 0.3 = 134
