The molarity of a sodium hydroxide (naoh) solution is 0.2 m. the molar mass of naoh is 40 g/mol. if the solution contains 20 g of sodium hydroxide dissolved in water, what is the volume of the solution?

Explanation:

1. Calculate the moles of NaOH.

2. Calculate the volume of NaOH

The 0.2M NaOH solution has a volume of 2.5 L

Explanation:

Step 1: Data given

Molarity of a NaOH solution = 0.2 M

Molar mass of NaOH = 40 g/mol

Mass of NaOH = 20.00 grams

Step 2: Calculate moles of NaOH

Moles = mass / molar mass

Moles NaOH = 20.00 grams / 40 g/mol

Moles NaOH = 0.50 moles

Step 3: Calculate volume

Molarity = moles / volume

Volume of solution = moles of NaOH / Molarity

Volume of solution = 0.50 moles / 0.2 M

Volume of solution = 2.5 L

The 0.2M NaOH solution has a volume of 2.5 L

the answer is barium and copper bromide
