The amount of water that could we get if you started with 250.0 grams of hydrogen is 2,250 grams.
<h3>What is moles - mass realation?</h3>
Moles (n) and mass of any substance are related to each other according to the given equation as:
n = W/M, where
W = given mass
M = molar mass
Given balanced chemical reaction is:
2H₂ + O₂ → 2H₂O
Moles of 250g of H₂ = 250g / 2g/mol = 125mol
From the stoichiometry of the reaction it is clear that,
2 moles of H₂ = produces 2 moles of H₂O
125 moles of H₂ = produces 125 moles of H₂O
Now mass of water will be calculated as:
Mass = (125mol)(18g/mol) = 2,250g
Hence required mass of water is 2,250 grams.

Speed is equivalent to the distance traveled divided by the time it takes to travel that certain distance.
To solve this problem convert the units first from meter and yards to miles. 100 metes is 0.0621371mi and 100 yards is 0.0568182 yard. 9.69s = 0.002691667 hr and 9.21s = 0.002558333
A.) 23mi/hr
B.) 22.20mi/hr
