Answer:

Three

Explanation:

Each C atom supplies four valence electrons and each O atom supplies six, for a total of 14 valence electrons.

If there are two double bonds (eight bonding electrons), there must be six nonbonding electrons (i.e., three lone pairs).

The Lewis structure of C₂O is :C=C=Ö:

What is the mass of calcium in 2.3•10^23 molecules of calcium phosphate
Katena32 [7]

Explanation:

N(Ca)=3×N(Ca₃(PO₄)₂)=

=3×2.3×10²³=6.9×10²³

6.02×10²³→40g

6.9×10²³→Xg

m(Ca)=X≈45.85g
