Answer:
add 7.5L of water
Explanation:
M1ĂV1=M2ĂV2
M is molarity, V is volume
0.7 Ă 10 = 0.4 Ă V2
V2= 17.5L
vol. of water to add= 17.5 - 10 = 7.5L
The volume which is required to prepare 0.4M lemonade is 17.5L.
How do we calculate the required volume?
Required volume of the solution will be calculated by using the below equation as:
MâVâ = MâVâ, where
Mâ & Vâ are the molarity and volume of initial lemonade.
Mâ & Vâ are the molarity and volume of final prepared lemonade.
On putting all values from the question, we get
Vâ = (0.7)(10) / (0.4) = 17.5 L
Hence required volume of final lemonade is 17.5 L.
