The number of grams of titanium that are in an instrument gear with 5.74 x10^22 atoms of Ti are calculated as below
find the number of moles of Ti that are in 5.74 x10^22 atoms
by use of Avogadro law constant, that is 1 mole = 6.02 x10^23 atoms
what about 5.74 x10^22 atoms
by cross multiplication
(1mole x5.74 x10^22 atoms)/6.02 x10^23 atoms = 0.0953 moles
mass of Ti =moles of Ti molar mass of Ti
that is 0.0953 moles x 47.87 g/mol = 4.562 grams of Ti
