Final answer:
To find the mass of a 1.6 mole sample of Li3PO4, multiply the number of moles by its molar mass. The molar mass of Li3PO4 is 115.79 g/mol, resulting in a mass of 185.264 grams for the sample.
Step-by-step explanation:
To calculate the mass of Li3PO4 in a 1.6 mole sample, we need to use the molar mass of Li3PO4. The molar mass of lithium phosphate (Li3PO4) is provided as 115.79 grams per mole (g/mol). Using the formula mass = moles × molar mass, we can determine the mass of the sample.
First, multiply the number of moles (1.6 moles) by the molar mass (115.79 g/mol) to get the mass of Li3PO4 in grams:
- mass = 1.6 moles × 115.79 g/mol
- mass = 185.264 grams
Therefore, a 1.6 mole sample of Li3PO4 would weigh 185.264 grams.
