Answer 1

I will help you

Answer 2

First you need to find the atomic masses for each element

Answer 3

For Sodium: 22.99
For Carbon: 12.01
For Oxygen: 12.00

Answer 4

Now we calculate (22.99)2+(12.01)1+(16.00)3 =

Answer 5

105.99 g/mol

Answer 7

No problem

Answer 8

- Make sure you have the correct chemical formula.
- Always include the units for molecular weight (grams/mole).
- Make sure you do the math right

Also: Molecular weight, molar mass, and gram formula mass are all the same thing.
