What is the molarity of the carbonate ion in sodium carbonate, Na2CO3, prepared by dissolving 3.5 g of sodium carbonate in enough water to form 0.800 L of solution?
Determine the pH of a buffer prepared by mixing 0.675 moles of HC2H3O2 and 0.575 moles of NaC2H3O2 in enough water to give 1.00 liter of solution.
A volume of 120 mL of H2O is initially at room temperature (22.0 C). A chilled steel rod at 2.00 C is placed in the water. If the final temperature of the system is 21.1 C , what is the mass of the steel bar?
