Given - Number of moles and volume
Find - New number of moles
Solution - The number of moles will be 3.75.
The number of moles and volume are related to each other by the formula - n1/V1 = n2/V2.
n1 is 2.5 moles and V1 is 500 millilitres. V2 is 750 millilitres.
Keep the values in the formula to find the value of the number of moles.
n2 = 2.5*750/500
n2 = 3.75
Thus, the number of moles, as per given information, will be 3.75.
