------------------------------------------------ How many grams of NaOH are needed to make 1.55 liters of a 1.55 molar solution?

Answer :

Answer:

Mass = 96g

Explanation:

Molarity = number of moles/volume of solvent

According to the provided information, volume = 1.55L, Molarity = 1.55M

number of moles (n) = molarity × volume

n = 1.55 × 1.55

n = 2.4025

n = 2.40mol

For NaOH, molar mass = 23 + 16 + 1 = 40g/mol

mole = mass/molar mass

Mass = molar mass × mole

Mass = 40 × 2.40

Mass = 96g
