We can calculate the percentage composition of tungsten in this chemical compound by the following formula:
formula: = Mass of element/total mass of compound x 100
Data:
mass of tungsten in grams=183.84 g/mol
mass of carbon in grams =12g/mol
Total mass of compound = 183.84 g/mol+ 12g/mol = 195.86 g/mol
Solution:
% of the tungsten= mass of tunsten/ total mass of compound x 100
= 183.84/195.86 x 100 = 93.87% or approx 94%
