How many grams of CaCl2 are needed to make 610.3 g of a solution that is 36.5% (mm) calcium chloride in water? Note that mass is not technically the same thing as weight, but (m/m) has the same meaning as (w/w). Number g Cac How many grams of water are needed to make this solution? Number b) What is the volume percent % v/ alcohol in 739 mL of water? (Assume that volumes are additive.) of an alcohol solution made...
Calculate the volumes of 0.20 M acetic acid and 0.20 M sodium acetate needed to make 20.00 mL of a buffer having pH = 5.00. Repeat analogous, separate calculations for buffers having pH = 4.00 and pH = 6.00. Hint: set up two equations with two unknowns; the first is the Henderson-Hasselbalch equation, the second is the fact that the volumes of HA (x mL) and A− (y mL) solutions should sum to 20 mL. In the Henderson-Hasselbalch equation, use...
