Answer:
C₄H₁₂
Explanation:
The empirical formula gives you your smallest whole number ratio for the elements in the compound. Find the molar mass using a periodic table. We have one carbon (12.01 g/mol) and three hydrogens (1.008 g/mol). Therefore our molar mass for the empirical formula is 12.01 + 3(1.008) = 15.034 g/mol. To find the molecular formula divide the given molar mass by the empirical formula's molar mass 60.2/15.034 = 4.004257017 = 4. This number is the amount to multiply the empirical formula by to get the molecular formula, therefore your molecular formula is C₄H₁₂
Answer:
We can say, there are 4 mol of oxygen with (4 . NA) = 2.40ₓ10²⁴ atoms
Or just, 4 atoms oxygen.
Explanation:
CH₄ + 2O₂ → CO₂ + 2H₂O
1 mol of methane reacts with 2 mol of oxygen to produce 1 mol of carbon dioxide and 2 mol of water.
We count in 1 mol of CO₂, we have 2 mol of oxygen
In 2 mol of water, we have 2 mol of oxygen.
We can say, there are 4 mol of oxygen with (4 . NA) = 2.40ₓ10²⁴ atoms
Or just, 4 atoms oxygen.
