How many atoms of mg are present in 97.22 grams of mg? 6.022 × 1023 2.408 × 1024 4.818 × 1024 5.855 × 1025

Second option

Explanation:

Number of atoms = Number of moles x Avogadro's Number

So first we need to find the number of moles in 97.22 grams of Mg.

Atomic Mass of Mg = 24

Number of moles = n = Given Mass / Atomic Mass

n = 97.22/24 = 4.05

Now we can calculate the Number of Mg atoms in 97.22 .

Number of atoms =

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
