Answer: 34.8 mol NH 3 3 mol H 2 2.02 g H 2 = 105 g H 2 2 mol NH 3 1 mol H 2 Key Questions: 8. What was the given in the example above? 9. Dec 14, 2018 · The correct answer is option B From the equation: 2C(s) + H2O (l) (CH4 (g) + CO2 (g) We can tell that 2 moles of carbon are required to react with water to form 1.00mol CH4. 12 grams of carbon is equal to 1 mole. There are more oxygen atoms in ozone (O 3) than there are in oxygen gas (O 2 ). You cannot calculate mole ratio for an unbalanced equation. Balancing this equation yields: 2O 3 → 3O 2. Now you can use the coefficients in front of ozone and oxygen to find the mole ratio. The ratio is 2 ozone to 3 oxygen, or 2:3. What Is a Mole Ratio?

From the coefficients of the equation, the mole ratio is 3:3. However, this reduces to a 1:1 ratio. That means that answer choice (a) would be considered by most teachers to be the correct answer. Please note that using a 3:3 ratio in a calculation is equivalent to using a 1:1 ratio. The same answer is obtained using 3:3 as opposed to using 1:1. First we determine the mole ratio (remember unknown species on top), H 2 S: H 2 = 8:8 = Number of moles of given species x mole ratio = number of moles required of unknown. So 3.5 x 1 = 3.5 moles of H 2 S could be produced.

Step 2: Calculate the mole:mole ratio. The smallest number of moles calculated corresponds to sodium so, divide all of the moles calculated by sodium’s number of moles, 0.5282 to obtain a simplified ratio. 0.5282molNa =1 0.5282molNa 0.5286molS =1 0.5282molNa 0.792molO =1.499=1.5 0.5282molNa Multiply all of the moles in the mole:mole ratio by 2 to obtain small whole numbers. The empirical The molar amount of a substance may be calculated by dividing its mass (g) by its molar mass (g/mol): The factor-label method supports this mathematical approach since the unit “g” cancels and the answer has units of “mol:”. 4.7 g K ( mol K 39.10 g) = 0.12 mol K. 4.7 g K ( mol K 39.10 g) = 0.12 mol K.
