The tungsten metal used for filaments in light bulbs is made by
reaction of tungsten(VI) oxide with hydrogen:
WO3(s)+3H2(g)→W(s)+3H2O(g)
The above reaction was performed and produced 2.20 g of
tungsten.
1. How many moles of tungsten were formed?
2. How many moles of tungsten(VI) oxide were required to produce the 2.20 g of tungsten?
3. How many moles of hydrogen were required to produce the 2.20 g of tungsten?
4. How many grams of tungsten(VI) oxide must you start with to prepare 2.20 g of tungsten? (For WO3, MW=231.8amu.)
5. How many grams of hydrogen must you start with to prepare 2.20 g of tungsten?
