Answer 1

Correct answer is : (E.) 3.7 g

Explanation

concentration KCl = 0.10 M

volume KCl solution = 0.500 L

moles KCl required = (concentration KCl) * (volume KCl solution in Liter)

moles KCl required = (0.10 M) * (0.500 L)

moles KCl required = 0.050 mol

mass KCl required = (moles KCl required) * (molar mass KCl)

mass KCl required = (0.050 mol) * (74.55 g/mol)

mass KCl required = 3.7 g
