Answer:
Molarity = 1.57 M
Explanation:
Given data:
Volume of solution = 350 mL (350 mL × 1L /1000 ml = 0.35 L)
Mass of NaCl = 32.0 g
Molarity of solution = ?
Solution:
Number of moles of solute:
Number of moles = mass/molar mas
Number of moles = 32.0 g/ 58.44 g/mol
Number of moles = 0.55 mol
Molarity:
Molarity = number of moles / volume in L
Molarity = 0.55 mol / 0.35 mL
Molarity = 1.57 mol/L
Molarity = 1.57 M
