Answer:
Explanation:0.493 M NaOH means 0.493 mol NaOH/L
mols
mols = ------ x L
L
mols = M x V
In a titration procedure, 40.57 mL of 0.493 M NaOH solution was used. How many mols NaOH did this volume of NaOH solution contain?
mols = M x V
0.493 mols NaOH
mols = ----------------------- x 0.04057 L
L
mols = 0.0200 mols NaOH
Answer:
0.5 moles
Explanation:
to get the number of moles, you have to divide the mass by molar mass.
the molar mass of carbon-12 is 12 u.
6 / 12 = 0.5
you have 0.5 moles
