What is the molarity of a solution made by dissolving 2.00 g of potassium chlorate in enough water to make 150. mL of solution?
What is the molarity of a solution made by dissolving 2.00 g of potassium chlorate in enough water to make 150. mL of solution?
Knowns mass KClO_3 = 2.00 g
volume = 150. mL
molar mass KClO_3 = 122.6 g/mol
Solution map: \frac{g KClO_3}{mL} → \frac{g KClO_3}{L} → \frac{mol KClO_3}{L} =M
CALCULATE (\frac{2.00 \cancel{g KClO_3}}{150. \cancel{mL}}) (\frac{1000 \cancel{mL}}{L}) (\frac{1 mol KClO_3 }{122.6 \cancel{g KClO_3}}) = \frac{0.109 mol}{L}
=0.109 M KClO_3
