Final answer:
To calculate the mass of calcium chloride needed to prepare a solution, you can use the concept of molar mass. The molar mass of calcium chloride (CaCl2) is 110.98 g/mol. First, convert the given moles of CaCl2 to grams using the formula: mass = moles x molar mass. Therefore, you would need 332.94 grams of calcium chloride to prepare the specified amount.
Step-by-step explanation:
To calculate the mass of calcium chloride needed to prepare a solution, you can use the concept of molar mass. The molar mass of calcium chloride (CaCl2) is 110.98 g/mol. First, convert the given moles of CaCl2 to grams using the formula:
mass = moles x molar mass
mass = 3.00 moles x 110.98 g/mol = 332.94 g
Therefore, you would need 332.94 grams of calcium chloride to prepare the specified amount.
