FREE Expert Solution

We’re being asked to determine the empirical formula of a compound composed of Na, S, and O given the mass percent of each element. This means we need to do the following steps:


Step 1: Calculate the mass and moles of Na, S, and O in the compound.

Step 2: Determine the lowest whole number ratio of Na, S, and O to get the empirical formula.


Step 1:  Recall that mass percent is given by:

% mass of X = mass of Xtotal massx100
