Final answer:
To find the mass of 1.73 moles of CaI2, multiply the number of moles (1.73) by the molar mass (176.124 g/mol) to get the mass in grams.
Step-by-step explanation:
The question is asking for the mass of 1.73 moles of CaI2 in grams. The molar mass of CaI2 is given as 176.124 g/mol. To find the mass of 1.73 moles, you would multiply the number of moles by the molar mass:
Mass = moles × molar mass
Mass = 1.73 mol × 176.124 g/mol
This calculation would result in the mass of the CaI2 sample.
