How many moles 500cm3 of 5.0M OF LITHIUM BROMIDE SOLUTION?

To find the number of moles in a 500 cm³ (or 0.500 L) solution of lithium bromide (LiBr) with a concentration of 5.0 M, you can use the formula:

[ \text{Moles} = \text{Molarity} \times \text{Volume (L)} ]

Substituting the values gives:

[ \text{Moles} = 5.0 , \text{M} \times 0.500 , \text{L} = 2.5 , \text{moles} ]

Therefore, there are 2.5 moles of lithium bromide in the solution.
