Final answer:
The mass of 1.34 moles of calcium chloride (CaCl2) is 148.71 grams, calculated by multiplying the number of moles (1.34) by the molar mass of CaCl2 (110.98 g/mol).
Step-by-step explanation:
To calculate the mass of 1.34 mol of calcium chloride (CaCl2), you can use the following steps:
- Determine the molar mass of CaCl2, which is given as 110.98 g/mol.
- Use the formula: mass = moles × molar mass. This means that you multiply the number of moles by the molar mass of the substance to find the mass.
- So for 1.34 moles of CaCl2, the calculation would be 1.34 moles × 110.98 g/mol.
- Doing this multiplication gives you the mass of CaCl2 in grams.
1.34 moles of CaCl2 × 110.98 g/mol = 148.71 grams of CaCl2. Therefore, the mass of 1.34 moles of CaCl2 is 148.71 grams.
