I did the work, but I need help checking it...
A compound contains 83.24% by mass carbon. Calculate the molar mass of the compound if it contains 5 moles of carbon per mole of compound.
This was my process:
I took 100g of compound and found that there are 83.24 g C in that much compound.
Then:
(83.24 g C) * (1 mol C / 12.011 g C) * (1 mol compound / 5 mol C) * (X g compound / 1 mol compound)
= 1.386 g compound
Is this correct..?
