Question

calculate the number of moles of cuso4 contained in 100mL of 1M cuso4 solution.also,find the number of so4^2- ions in it.​

Answer 1

Answer:

Hey its simple

Explanation:

M(molarity) =no. of moles of given solute/ Volume in litre

1. so,, 1M=n/100/1000
2. = 10n
3. n =1/10 .
4. this is the required answer.

2) No of so4- ions = n * NA( Avogadro's number)

=1/10 * 6.022*10^23

= 6.022*10^22 Answer.

MAY U WILL EASILY UNDERSTAND.☺.

if any problem then comment i will answer.
