In order to calculate the number of atoms, we must first know the number of moles present. And
moles = (mass present) / (molecular mass)
Therefore, the moles of Mg present are
170 / 24 = 7.08
The number of atoms in a mole of substance is given by Avagadro's Number which is 6.02 x 10^23
Since there are 7.08 moles, there are:
7.08 * 6.02*10^23
= 4.26 * 10^24 atoms
This is true, the force can bring land up at ease
Explanation:
1 sulfur dioxide 2 monosulfur dinitride 10 nitrogen dioxide
12.01 amu
Work:
(12.000 × .9889) + (13.003 × .0111) = 12.01
- turn the precents into decimals
