How many moles are in 8.8 x 1024 atoms of magnesium?
Veseljchak [2.6K]

Answer:

15 mol Mg

Explanation:

Step 1: Find conversions

Avagadro's Number: 6.022 × 10²³

Step 2: Use Dimensional Analysis

8.8(10)^{24} \hspace{3} atoms \hspace{3} Mg(\frac{1 \hspace{3} mol \hspace{3} Mg}{6.022(10)^{23} \hspace{3} atoms \hspace{3} Mg} ) = 14.6179 mol Mg

Step 3: Simplify

We have 2 sig figs.

14.6179 mol Mg ≈ 15 mol Mg

White phosphorous has the chemical formula p4(s). a p4 molecule has 20 valence electrons. draw a lewis formula for a white phosp
aev [14]
The Lewis structure of P₄ is shown in 3-D form. The two bottom corner P atoms are facing right in front of us, one P atom behind the two, and one P above it. Each line represents 2 electrons. When you add the lone electrons, you get a total of 20 valence electrons.

Formal charge of each P:  5 - (2 +1/2*6) = 0
