QUESTION
How can I find the percent compositions of NaOH?
- Find the different atomic masses of the that are present. ##Na - 23## ##O - 16## ##H - 1##
- Find the molecular mass of ##NaOH##. ##23+16+1=40##
- Divide each element's by the compound's molecular mass then multiply the number by 100.
For ##Na## ##23/40*100=57.5%##
For ##O## ##16/40*100=40%##
For ##H## ##1/40*100=2.5%##
