Question

35 g of NaOH are dissolved in water to make 3872 mL of a NaOH solution. Use 40 for the molecular weight of NaOH. What is the

Answer 1

Answer #1

So you have:

number of moles = amount / molecular weight = 35/40 = 0.875 moles.

Molarity = no. of moles/ volume in L. = 0.875x1000(for mL) / 3872 = 0.226 M.

So the concentration is 0.226 molar.
