Question

Calculate The gram molecular masses of the following A)cacO3 B)H2O2? Thanks

Answer 1

We simply sum up the atomic masses of each constituent element....

Explanation:

And have you got a Periodic Table beside you? For `CaCO_3`, we take...

`{1xx40.1+12.011+3xx16.0}*g*mol^-1=100.09*g*mol^-1`....

Can you do the same for hydrogen peroxide, given that the atomic mass of hydrogen is `1.00794*g*mol^-1`, and that of oxygen is `16.00*g*mol^-1`...??
