A chemist adds of a M calcium sulfate solution to a reaction flask. Calculate the mass in grams of calcium sulfate the chemist has added to the flask

1.23 g

Explanation:

A chemist adds 1.55 L of a 0.00582 M calcium sulfate solution to a reaction flask. Calculate the mass in grams of calcium sulfate the chemist has added to the flask.

Step 1: Given data

Step 2: Calculate the moles (n) of calcium sulfate added

We will use the following expression.

n = C × V

n = 0.00582 mol/L × 1.55 L

n = 0.00902 mol

Step 3: Calculate the mass corresponding to 0.00902 moles of calcium sulfate

The molar mass of calcium sulfate is 136.14 g/mol.

0.00902 mol × 136.14 g/mol = 1.23 g

water is used to store them because it would keep the radiation from getting out in the open and causing harm to the workers
