What is the mass in grams of 4.4 moles of the element tungesten, W?​

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

809.6g is your answer

1 mole of tungsten =184 g

4.4 mole of tungsten =184×4.4=809.6g

? you expect us to answer this? ? this is your schoolwork, i don't think we can with this, i think it would considering being
