A chemist prepares a solution of calcium sulfate CaSO4 by measuring out 0.03g of calcium sulfate into a 150.mL volumetric flask and filling the flask to the mark with water. Calculate the concentration in /molL of the chemist's calcium sulfate solution. Be sure your answer has the correct number of significant digits.

0.00147 Molar is the molarity of the solution.

Explanation:

Molarity of the solution is the moles of compound in 1 Liter solutions.

Mass of calcium sulfate = 0.03 g

Molar mass of calcium sulfate = 136 g/mol

Volume of the calcium sulfate = 150. mL = 0.150 L ( 1 L = 0.001 mL)

0.00147 Molar is the molarity of the solution.

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).
