Calculate the moles and the mass of solute in 500.0 mL of 2.00 M HCl.

Question

Quizplus · Accepted Answer

We can use the formula:

moles = M x L

where M is the concentration in mol/L and L is the volume in L.

Substituting the values given:

moles = 2.00 mol/L x 0.5000 L = 1.00 mol

Therefore, the answer is (C) 1.00 mole.

To find the mass of solute, we can use the formula:

mass = moles x molar mass

where molar mass is the mass of 1 mole of the substance. For HCl, the molar mass is 36.5 g/mol.

Substituting the values:

mass = 1.00 mol x 36.5 g/mol = 36.5 g

Therefore, the answer is also (C) 36.5 g.
