A12.41 g sample of nabr contains 22.34% na by mass. considering the law of constant composition (definite proportions) how many grams of sodium does a 8.99 g sample of sodium bromide contain?

Explanation:

Hello,

In this case, given the by mass percent of sodium in sodium bromide::

Solving for the mass of sodium, considering the constant composition of sodium in the sodium bromide, we obtain:

Best regards.
