Question

Question 2 (2 points) Which of the following is true about finding the molar mass of potassium sulfate, K2SO4?

The molar mass is found by adding the molar mass of K, to the molar mass of sulfate.

The molar mass is found by taking 2 x the molar mass of K, plus 1 x the molar mass of sulfur, plus 4 x the molar mass of oxygen

The molar mass is found by using Avogadro's number divided by 22.4.

The molar mass of potassium sulfate is a number between 1 and 10.
