The answer is #67.6# #g#.

First, start with the balanced chemical equation

#Bi_2O_(3(s)) + 3C_((s)) -> 2Bi_((s)) + 3CO_((g))#

We know the molar masses of #Bi# (#209g/(mol)#) and #Bi_2O_3# (#466g/(mol)#), and the mole-to-mole ratio between #Bi# and #Bi_2O_3#, so we could say that

#60.7gBi* (1 mol e Bi)/(209g) * (1 mol e Bi_2O_3)/(2 mol es Bi) * (466g)/(1 mol e Bi_2O_3) = 67.6g Bi_2O_3#
