Tungsten carbide is becoming popular for making jewelry. a chemist is examining a sample of tungsten carbide (chemical formula wc). what is the percent composition of tungsten in this compound? round your answer to the nearest whole percent.

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%
