Question

how many liters of 4 M solution can be made using 10 moles of lithium bromide LiBr?

Answer 1

do you know what the "M" in "4 M" stands for?

Answer 2

a 4 M solution is basically that in every 1 litre of solution....4 moles of the substance are present....
\[Molarity=moles/litre\]
therefore...in 1 litre...there are 4 moles
in 10 litres...there are (10/4) moles=2.5 moles

Answer 3

thanks

Answer 4

"in 10 litres...there are (10/4) moles=2.5 moles"

you mean with 10 moles you can make 2.5 L.
