a) 72.04 g b) 7.75 g c) 614.8 g

Work Step by Step

Mass in grams = Number of moles$\times$ Molar mass. a) Mass in grams of Ti = $1.505 mol\times47.867g/mol$ = 72.04 g b) Mass in grams of Na = $0.337 mol\times\frac{22.99g}{mol}$ = 7.75 g c) Mass in grams of U = $2.583 mol\times\frac{238.029g}{mol}$ = 614.8 g
