N2H4 (1) --> N2 (g) + 2 H2 (g) 2 H2(g) + O2 (g) --> 2 H20 (1)
- If you lost some of your hydrogen gas during your reaction and only produced 7.25 g of H2
(g) how many grams of water will you produce?
1g = 1ml and 1 L = 1000 ml
- How many liters of water will this produce?
- Watney needs 618L of water to survive on Mars until the next mission arrives and can
rescue him. Does 7.25g of H2 produce enough water for him to survive?

How many moles of gas are present if p=11 atm, v=12l, t=185k?

Word equation for k(s)+h2o(l) yield koh(aq) + h2(g)
