Calculate the molar mass of sodium oxide (Na2O) using the periodic table. Type in your answer usingtwo decimal places.g/mol

Sagot :

Explanation:

First, we need to find the atomic mass of Na and O in the periodic table.

Na: 22.99 g/mol

O: 15.99 g/mol

So we multiply the atomic mass by the number of atoms of each element. In Na2O we have 2 atoms of Na and 1 atom of O.

Na: 2 * 22.99 = 45.98

O: 1 * 15.99 = 15.99

Sum the results: 61.97 g/mol

Answer: The molar mass of Na2O is 61.97 g/mol
