A chemist adds 485 mL of a 0.0025 mol/L calcium sulfate solution to a reaction flask. Calculate the mass in grams of calcium sulfate the chemist has added to the flask. Round your answer to significant digits.

Answer : The mass in grams of calcium sulfate is 0.16 grams.

Explanation :

Molarity : It is defined as the number of moles of solute present in one litre of solution.

Formula used :

Solute is,

Given:

Molarity of = 0.0025 mol/L

Molar mass of = 136 g/mole

Volume of solution = 485 mL

Now put all the given values in the above formula, we get:

Thus, the mass in grams of calcium sulfate is 0.16 grams.
