Look up the atomic masses on the periodic table and add them together to obtain the molar mass.
For example, HNO3, is approximately
H = 1
N = 14
O = 16 and we have three of them; therefore, 3 x 16 = 48.
Then 48 + 14 + 1 = 63.
I have rounded here and there; therefore, you need to confirm this.
Post your answers to the others if you want someone to check them.
Can someone please explain how to determine the molar mass of the following
nitric acid(HNO3)
ammonium nitrate(NH4NO3)
zinc oxide(ZnO)
Cobalt chloride(CoCl2)
thanks
