Molarity = moles / 1000 cm³
When we dilute the solution we get a total volume of :
250 ml + (5 × 1000) ml = 5250 ml
Which is 5250 cm³
1.5 moles are in 1000 cm³
How many moles are on 250 ml:
(250 / 1000) × 1.5 = 0.375 moles.
These moles are in 5250 cm³
The molarity is thus :
(1000 / 5250) × 0.375 = 0.07143 M
When we dilute the solution we get a total volume of :
250 ml + (5 × 1000) ml = 5250 ml
Which is 5250 cm³
1.5 moles are in 1000 cm³
How many moles are on 250 ml:
(250 / 1000) × 1.5 = 0.375 moles.
