Question

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

Answer 1

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.
