Question 92

The equation shows the extraction of tungsten from tungsten(VI) oxide using hydrogen gas.

WO3+3H2→W+3H2O \text{WO}_3 + 3\text{H}_2 \rightarrow \text{W} + 3\text{H}_2\text{O} WO3​+3H2​→W+3H2​O

Calculate the maximum mass of tungsten, W\text{W}W, that could be produced from 580 kg of tungsten(VI) oxide, WO3\text{WO}_3WO3​.

(Relative formula masses: WO3=232\text{WO}_3 = 232WO3​=232, W=184\text{W} = 184W=184)
