How many atoms are in 4.9 moles of Sodium (Na)? a
112.7 atoms
b
6.022 X 10 ^ 23 atoms
c
2.95 X 10 ^ 24 atoms
d
8.14 X 10 ^ -24 atoms

C.) 2.95 x 10^24

Explanation:

make a ratio

1 mole = molar mass x 6.023 x 10^23

# moles = x

1 mole= 22.9 x 6.023 x 10^23

4.9 moles= x

cross multiply

then divide

= 2.95 x 10^24
