(a)
Interpretation:
The number of grams of solute present in
Concept introduction:
Several concentration units may be used to express the concentration. It is often useful to express the concentration in terms of percentage. This can be expressed as the amount of solute in grams dissolved in
The formula to calculate molarity is given as follows:
The formula to determine the mass from number of moles is as follows:
Answer to Problem 63P
The number of grams of
Explanation of Solution
The formula to calculate molarity is given as follows:
Since the units of molarity are
