The tungsten metal used for filaments in light bulbs
is made by reaction of tungsten(VI) oxide with
hydrogen:
WO3(s) + 3 H2(g) → W(s) + 3 H2O(9)
The above reaction was performed and produced
3.34 g of tungsten.
How many moles of tungsten(VI) oxide were required to produce the 3.34 g of tungsten?
How many moles of hydrogen are required to produce the 3.34 g of tungsten
How many grams of tungsten (VI) oxide must you start with to prepare 3.4 g of tungsten? ( for WO3, MW=231.8
