Does anyone know how to find mass of NaN3?
Alexus [3.1K]
The molar mass (atomic weight ) of sodium is 23.0 grams/mole and the molar mass of sodium azide, NaN3 , is the mass of sodium, 23.0 gram/mole added to the molar mass of three atoms of nitrogen (14.0 x 3 = 42 gram/mole) which equals 65.0 grams/mole. The percentage of sodium is 23.0 /65.0 x 100 % = 35 %

Calculates the equivalent mass of calcium chlorate CA (CI03) 2
love history [14]

Answer:

207g

Explanation:

Given compound:

            Ca(ClO₃)₂

The equivalent mass can be derived by summing the molar masses of each atom

  Molar mass of Ca = 40

                            Cl  = 35.5

                            O  = 16

Now solve;

 Molar mass  = 40 + 2(35.5 + 3(16)) = 207g
