Answer: The final concentration when 5 ml of a 2.5M copper sulphate solution is diluted to 750 ml is 0.017 M
Explanation:
According to the dilution law,
where,
= molarity of stock
solution = 2.5 M
= volume of stock
solution = 5 ml
= molarity of diluted
solution = ?
= volume of diluted
solution = 750 ml
Putting in the values we get:
Therefore the final concentration when 5 ml of a 2.5M copper sulphate solution is diluted to 750 ml is 0.017 M
#1
- As 2 electrons are donated Hence the No of electrons =38-2=36
#2
- As 3 electrons donated the no of electrons=23-3=20
#3
- No of neutrons=55-26=29
#4
- As 2 electrons are donated no of electrons =48-2=46
#5
- No of neutrons=210-82=128
