There are approximately
We must first find the molar mass of sodium bicarbonate,
We do this as follows:
1) Find the molar mass of each element in the compound.
#"Na = 22.99 g/mol"#
#"H = 1.008 g/mol"#
#"C = 12.01 g/mol"#
#"O = 16.00 g/mol"#
2) Add up the molar masses to find the molar mass of the compound.
This means that each mole of sodium bicarbonate weighs about
3) Divide the number of grams by the molar mass to find moles.
Note: Keep in mind that you have one significant figure for the mass of sodium bicarbonate!
