Explanation:
Answer: 118.5 grams
Explanation:
Molarity is defined as the number of moles of solute dissolved per liter of the solution.

where,
n= moles of solute
= volume of solution in ml = 500 ml

moles = 0.75
moles of solute =
0.75 =
mass of
= 118.5 grams
Thus mass of
needed to prepare 500 mL of this solution iis 118.5 grams
