Answer 1

For Plato users the answer is 94%

Step-by-step explanation:

Answer 2

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%
