Find the Mass of a Single Atom Mg

$M g$

Step 1

To calculate the mass of a single atom, first look up the atomic mass of $M g$ from the periodic table. This is also the mass in grams of 1 mole of $M g$ .

$24.31$

Step 2

Use Avogadro\'s number to find the mass of a single atom.

$\frac{24.31}{6.022 \cdot 10^{23}}$

Step 3

Divide using scientific notation.

Group coefficients together and exponents together to divide numbers in scientific notation.

$(\frac{24.31}{6.022}) (\frac{1}{10^{23}})$

Divide $24.31$ by $6.022$ .

$4.03686482 \frac{1}{10^{23}}$

Move $10^{23}$ to the numerator using the negative exponent rule $\frac{1}{b^{n}} = b^{- n}$ .

$4.03686482 \cdot 10^{- 23}$
