Final answer:
To convert 0.24 mol of lithium to mass, multiply the number of moles by lithium's molar mass (6.94 g/mol), resulting in 1.6656 grams of lithium.
Step-by-step explanation:
To convert 0.24 mol of lithium (Li) into mass, we need to use the molar mass of lithium. The molar mass of Li is approximately 6.94 g/mol. By multiplying the number of moles by the molar mass, we get the mass in grams:
0.24 mol Li × 6.94 g/mol Li = 1.6656 g Li
Therefore, 0.24 moles of lithium is equivalent to 1.6656 grams of lithium. This calculation assumes that the atomic weight of lithium is accurate to two decimal places as per standard atomic weights. When dealing with significant figures, the answer may need to be rounded accordingly based on the precision of the given values.
