5.0 mol Li * 6.941 g/mol Li = 34.705 = 35 g Lithium
For an element such as lithium, the technically correct term is "gram atomic mass" instead of "mole", and for lithium, the gram atomic mass is about 6.941. Therefore, the answer to the question is (5.48)(6.941) or 37.5 grams, to the justified number of significant digits.

Chemical Engineers sometimes measure substance amount in units of gram-moles, kilogram-moles, pound-moles, or ounce-moles; these measure the quantity of a substance whose molecular weight is not equal to its mass in grams, kilograms, pounds, or ounces. The SI mole is identical to the gram-mole. This is from wikipedia entry on moles. So 1 mole = 1 gram-mole
Since the gram atomic mass of calcium is 40.08 and calcium does not form polyatomic molecules, the number of moles in 40g of calcium is 1.0, to the justified number of significant digits.
This conversion requires a specific element. To convert moles to gram, you need to take the number of moles and multiply it by the atomic mass. If you do not have the atomic mass, you cannot go from moles to gram or grams to moles.
