7 0

Answer:

27.06%

Explanation:

First let us calculate the molar mass of NaNO3. This is illustrated below:

MM of NaNO3 = 23 + 14 + (16x3) = 23 + 14 + 48 = 85g/mol

Now, we see that NaNO3 contains 1atom of Na.

Therefore the percentage composition of Na in NaNO3 is given by:

(23/85) x 100 = 27.06%
