Question

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. The percent composition of tungsten is %

Answer 1

% composition of tungsten ( W) = 93.86%

solution is attached below

Answer 2

The percent composition of W in WC is 93.868 %.

MM of WC = 183.84 u + 12.01 u = 195.85 u

% W = Mass of W/Mass of WC × 100 % = 183.84 u/195.85 u × 100 %

= 93.868 %.
