Answer:
C. 114.8 u
Explanation:
The atomic mass of X is the <em>weighted average</em> of the atomic masses of its isotopes.
We multiply the atomic mass of each isotope by a number representing its relative importance (i.e., its percent of the total).
Set up a table for easy calculation
0.0429 × 112.90 u = 4.843 u
0.9571 × 114.90 u = <u>109.97 u
</u>
TOTAL = 114.8 u

Answer: Hello!
first i believe we need a balanced equation to start...
i got 2H2 + 1O2 = 2H2O
This tells us that we need 2 moles of H2 for every 1 mole of O2 Since we only have 1 mole of H2 compared to the 5 moles of O2 hydrogen is the limiting reagent. For illustration, divide the balanced equation by 2 in order to get 1 mole of H2 If we start with 1.0 moles of H2 we'll produce 1.0 mole of H2O
