A 100.0-g sample of sodium hydroxide contains sodium, oxygen, and hydrogen. The sample contains 2.53 g of hydrogen and 40.0 g of oxygen. What mass of sodium is in
the sample? (Record your answer as a 3 digit number)

57.47 grams of sodium is in the sample.

Explanation:

Given that a 100.0-g sample of sodium hydroxide contains sodium, oxygen, and hydrogen, and the sample contains 2.53 g of hydrogen and 40.0 g of oxygen, to determine what mass of sodium is in the sample the following calculation must be performed:

100 - (40 + 2.53) = X

100 - 42.53 = X

57.47 = X

Therefore, 57.47 grams of sodium is in the sample.
