The given question is incomplete. The complete question is:
A chemist adds 0.85 L of a 0.0050M calcium sulfate 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 the chemist has added to the flask is 0.58 g
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.
where,
n = moles of solute
= volume of solution in L
moles of =
Now put all the given values in the formula of molarity, we get
Therefore, the mass in grams of calcium sulfate the chemist has added to the flask is 0.58 g
