what is the mass in grams?
a) 3.011 x 10^23 atoms F
b)1.50 x 10^23 atoms Mg
c)4.50 x 10^12 atoms Cl
d)8.42 x 10^18 atoms Br
e) 25 atoms w
f) 1 atom Au
can you please explain a and b to me then i'll come back later and see if i did the rest right? Thanks in advance

Use stochiometry
a) Molar mass F = 19g/mol
so...
(3.011 x 10^23 atoms F) X (1molF/(6.022 x10^23atoms)X (19g/1mol F) = 9.5 g F
(1molF/(6.022 x10^23atoms) = Avogardro's Law can be used in any situation such as this. Use it for the rest of the questions listed in the same way shown above.
