Question

carbon dioxide, _________,_________ Write the chemical formula and number of atoms in the following compounds.

Answer 1

Answer:

chemical formula: CO2 ( subscript 2)

no. of atoms in one mole: 6.022 * 10²³ atoms.

Explanation:

you will have to give the amount of a compound to find its no. of atoms. Since no exact amount was given, the amount of atoms in 1 mole (44g) is given.

there is how it is 44g.

We know that,

atomic mass of Carbon (C)=12

atomic mass of Oxygen(O)=16

therefore,

molecular mass of CO2= (1*C) +(2*O)

12+32=44 amu.

Since mole is calculated in mass, 44 amu becomes 44 gms.
