Answer:
Explanation:
no. of moles of butane = 5.87g / 58.124 = 0.1009mol
since O2 is excess, limiting reagent is butane
from the equation, 2 moles of butane will reacted to produce water = 10 moles
therefore, 0.1009 moles of butane produced water = (0.1009 x 5) = 0.5050 moles
Weight of H2O formed = 0.5050 x 18.015 = 9.10 grams
NH3. Ammonia is composed of one nitrogen atom, and three hydrogens.
Mass number is the mass number of that particular Element found in the periodic table and the atomic number is the atomic no. Again found in the periodic table
