You should know that 1 mole has 6.02 x 10*23 atoms (Avogadro)...so if you have one atom with 4.48 *10-23 g...then 6.02 *10*23 how many??.. try the rule of 3...answer A is 26,9696 g. For answer b, first of all covert the 5000 kg to 5000000 g (you can write 5 x 10*6)..afterwards make the rule of 3.. if 26,9696 g they are in 1 mole, the mass of the plane 5 x 10*6 g... how many moles?.. be careful with g and the kg.!!.. Answer B should be 185393, 92 moles.
