Lab Report #10 Synthesis of Calcium Carbonate
Questions
Order the steps required to predict the volume (in mL) of 0.100
M sodium carbonate needed to produce 1.00 g of calcium carbonate. There is an excess of calcium chloride.
Step 1 : Convert mass of calcium carbonate to moles of calcium carbonate.
Step 2 : Compare moles of calcium carbonate to moles of sodium carbonate based on balanced equation to calculate moles of sodium carbonate required.
Step 3 : Compute the volume of sodium carbonate solution required.
Step 4 : Convert the volume of sodium carbonate solution required from liters to milliliters.
