🤓 Based on our data, we think this question is relevant for Professor Kummel's class at UCSD.

Solution: 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?

Problem

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?
