What is the mass of 3.0 x 10^23 atoms of neon
kari74 [83]
Molar mass neon = <span>20.1797 g/mol

20.1797 g ---------- 6.02x10</span>²³ atoms
         ? g ------------ 3.0 x 10²³ atoms

mass = 3.0 x 10²³ *  <span>20.1797 / 6.02 x 10</span>²³

mass = 6.054x10²⁴ / 6.02 x 10²³

mass = 10.05 g

hope this helps!
