🤓 Based on our data, we think this question is relevant for Professor Kummel's class at UCSD.
The tungsten metal used for filaments in light bulbs is made by reaction of tungsten trioxide with hydrogen:
WO3 (s) + 3H2 (g) → W(s) + 3H2O(g)
How many grams of tungsten trioxide must you start with to prepare 1.30 g of tungsten? (For WO3, MW = 231.8 amu.)
How many grams of hydrogen must you start with to prepare 1.30 g of tungsten?
