Answer 1

Answer:

The Molarity of a solution is determined by the comparison of the moles of the solute compared to the volume of the solution in liters.

mol

The equation of the formula is M = L In order to find the mass we first need to solve

for the moles.

mol M L -

M = 0.400 moles = ?

L = 250.0mL or 0.25 L

0.400M (0.25L) = (?mol)

0.100molof NaOH

Now we can calculate the grams be converting moles to grams.

Na = 22.98g

O = 15.99 g0 = 15.99g H = 1.01 gH = 1.01g

NaOH = 39.98 gNaOH = 39.98g

0.100 cancel(mol NaOH) x (39.98 g NaOH)/(1 cancel(molNaOH)

0.100 molNaOH x 39.98gNaOH 1molNaOH
