Answer:
4 M
Explanation:
Molarity refers to the molar concentration of a substance (solution). It can be calculated by using the formula below:
Molarity (M) = number of moles (n) ÷ volume (V)
According to the information provided in this question;
V = 0.4 liter
n = 1.6 moles
Molarity = n/V
Molarity = 1.6/0.4
Molarity = 4 M
