Question

The percentage of oxygen NaOH is​

Answer 1

Answer:

40.000%

40.000%The percent composition of oxygen in sodium hydroxide is 40.000%

Answer 2

Answer:

The percent composition of oxygen in sodium hydroxide is 40.000%

Determine the molar mass of sodium hydroxide  ( NaOH )  Then divide the molar mass of oxygen by the molar mass of  

NaOH  and multiply by 100.

O :15.999 g/mol  (periodic table) Percent Composition of Oxygen  percent composition

= 15.999  g  mol  39.997 g  mol × 100 = 40.000%
