Identify 3 statements that are true about potassium carbonate by checking the box in front of each true statement.

		The molar mass of potassium carbonate is 99.1 g/mol .
		The percent by mass of carbon (%C) in potassium carbonate is 8.69 % .
		The percent by mass of oxygen (% O) in potassium carbonate is greater than the percent by mass of potassium (% K) in potassium carbonate.
		There are 27.6 g of potassium carbonate in 0.200 mol of potassium carbonate.
		Different samples of pure potassium carbonate will always contain a different percent by mass of carbon (% C).
		A substance that is 56.6% potassium by mass could be pure potassium carbonate.
