Question

calculate the atomic mass of Nacl and co2​

Answer 1

Explanation:

We can calculate the mass of one molecule of carbon dioxide by adding together the masses of 1 atom of carbon and 2 atoms of oxygen. The molecular mass of a compound is the mass of one molecule of that compound. The molecular mass of carbon dioxide is 44.01amu.To calculate the molar mass of a compound with multiple atoms, sum all the atomic mass of the constituent atoms. For example, the molar mass of NaCl can be calculated for finding the atomic mass of sodium (22.99 g/mol) and the atomic mass of chlorine (35.45 g/mol) and combining them.

Answer 2

Explanation:

Q1:NaCl

Data:

Atomic mass of Na=23

Atomic mass of Cl=35.5

Solution:

Atomic mass of NaCl=Atomic mass of Na + Atomic mass of Cl

=23+35.5

=58.5

Q2:CO2

Data:

Atomic mass of C=12

Atomic mass of 2 O atoms=2×16=32

Solution:

Atomic mass of CO2=Atomic mass of C + Atomic mass of 2 Oxygen atoms

=12 +32

=44
