Answer:
0.97 grams
Explanation:
number of molecules=no of moles × Avogadros number
so
number of moles=nu.of molecules ÷ 6.02×10power23 = 1.98×10power21 ÷ 6.02×10p23=0.0033 mol
mass=nu.of moles× molar mass
molar mass of aspartame=
(14×12)+18+(2× 14.0067n)+(5×16)=294.0134 u
mass = 0.0033 ×294.0134 =0.97 gram
B)
Lithium=li
Iron=Fe
