What is the volume of solution with 0.82g/L concentration when the mass of the solute is 7g?
1 Answer
Explanation:
The idea here is that the concentration of the solution tells you the number of grams of solute present for every
This solution is said to have a concentration of
Now, you know that you have a sample of this solution that contains
Consequently, you can use the concentration of the solution to determine how many liters would contain
#7 color(red)(cancel(color(black)("g solute"))) * overbrace("1 L solution"/(0.82color(red)(cancel(color(black)("g solute")))))^(color(blue)("= 0.82 g L"^(-1))) = color(darkgreen)(ul(color(black)("9 L solution")))#
The answer is rounded to one significant figure, the number of sig figs you have for the mass of the solute.
