How do I get the molar mass of urea?
Answer:
I get \(60.06 \mathrm{~g} / \mathrm{mol}.\) Of course, you could get the same thing, but you would still have to look up the chemical formula anyways…
With known atomic masses…
\(\mathrm{H}: 1.0079 \mathrm{~g} / \mathrm{mol}\)
\(\mathrm{N}: 14.007 \mathrm{~g} / \mathrm{mol}\)
\(\mathrm{C}: 12.011 \mathrm{~g} / \mathrm{mol}\)
\(\mathrm{O}: 15.999 \mathrm{~g} / \mathrm{mol}\)
we get:
