What is the final volume in milliliters when 0.698 of a 42.2 (m/v) solution is diluted to 21.1 (m/v)?
I suppose 42.2 and 21/1 are percents but what is 0.698?
To find the final volume, you can use the formula:
(Volume1) x (Concentration1) = (Volume2) x (Concentration2)
Let's assign the values given in the problem to the variables:
Volume1 = 0.698 (amount of solution 1)
Concentration1 = 42.2 (m/v)
Volume2 = ?
Concentration2 = 21.1 (m/v)
Now we can substitute the values into the formula and solve for Volume2:
(0.698) x (42.2) = (Volume2) x (21.1)
To solve for Volume2, divide both sides of the equation by 21.1:
(0.698 x 42.2) / 21.1 = Volume2
Calculating the right side of the equation:
(29.3956) / 21.1 = Volume2
Volume2 ≈ 1.394 milliliters
Therefore, the final volume when 0.698 of a 42.2 (m/v) solution is diluted to 21.1 (m/v) is approximately 1.394 milliliters.
