To determine which has the greatest mass, we need to find out the molecular mass of each element:
Uranium (U) = 238 g/mol
Oxygen (O) = 16 g/mol
Sodium (Na) = 23 g/mol
Chlorine (Cl) = 35.45 g/mol
Therefore, if we have one mole of each element, the element with the greatest mass is 238 grams or <u>Uranium.</u><span />
Answer:
I never thought of it as a tool, but I think you refer to Atomic Weight. The total atomic weight of the atoms in a molecule is its Mass in Moles.
Take a really simple example H2O. The atomic weight of Oxygen is 16, Hydrogen is 1, and so added, 1 + 1 + 16 = 18; the mass of 1 mole of water is 18g. Same for Benzene, C6H6; atomic weight of carbon is 12, so 6 x 12 = 72, add 6 x 1, or 6, and 72 + 6 = 78
Explanation: The sum of the atomic weights of the atoms in a molecule will give you the Molecular Weight, I.e. the Mass of 1 Mole of thst molecule.
Answer:
6.8 mole of O₂
Explanation:
Given expression:
2H₂ + O₂ → 2H₂O
Number of moles of H₂ = 13.6moles
Unknown:
Number of moles of O₂ = ?
Solution:
In the given problem, we are to find the number of moles of oxygen gas that will use up 13.6mole of hydrogen gas;
From the reaction equation;
2 mole of H₂ will completely react with 1 mole of O₂
13.6 moles of H₂ will completely be used up by
mole of O₂
= 6.8 mole of O₂
Answer:
6CO2 + 6H20 ----> C6H12O6 + 6O2
Explanation:
(Carbon Dioxide) + (Water) ------> (Glucose) + (Oxygen)
Answer:
Graphite is insoluble in water and organic solvents - for the same reason that diamond is insoluble. Attractions between solvent molecules and carbon atoms will never be strong enough to overcome the strong covalent bonds in graphite. conducts electricity.
