Answer:
806.96 g
Explanation:
From the question,
Using,
No. of mole = reacting mass/molar mass.
n = R.m/m.m....................... Equation 1
make R.m the subject of the equation
R.m = molar mass of tungsten × number of mole of tungsten.................. Equation 2
Given: number of mole of tungsten = 4.4 moles
Constant: Molar mass of tungsten = 183.8 g/mol
Substitute these values into equation 2
Therefore,
mass of tungsten = 4.4×183.4
mass of tungsten = 806.96 g
