If the precipitate of CaSO4 was weighed before all of the
water has evaporated, therefore this will lead to a miscalculation on the
number of moles of CaSO4. During the calculation, the mass of the water will be
included hence there will be higher number of moles than what is correct.
V2 = 250 ml
Explanation:
Given:
P1 = 0.99 atm. V1 = 240 ml
P2 = 0.951 atm. V2 = ?
We can use Boyle's law to solve for V2
P1V1 = P2V2
V2 = (P1/P2)V1
= (0.99 atm/0.951 atm)(240 ml)
= 250. ml
