Question

PLEASE HELP ME FAST!! How many moles are contained in 500 mL of a 3.5M NaOH solution?

Answer 1

Answer:

1.75moles

Explanation:

Molarity = number of moles (n) ÷ volume (V)

According to the information given in this question,

V = 500mL = 500/1000 = 0.500L

n = ?

Molarity = 3.5M

Using Molarity = n/V

number of moles (n) = V × molarity

n = 0.5 × 3.5

n = 1.75moles.
