In order to know the number of moles from the given mass, the conversion factor to be used is the average atomic mass of Calcium which is equal to 40.08 g/mol. But first, let's convert mass from grams to kilograms knowing that there are 1,000 g in every 1 kg.
Mass = 351 kg * 1,000g/1 kg = 351,000 grams
Number of moles = 351,000 g * 1 mol/40.08 g = 8,757.5 moles Calcium
Answer:
Empirical formula of 81.8 carbon and 18.2 hydrogen
Steps
- Find the empirical formula of a compound that has 81.8% of Carbon (C), 18.2% of Hydrogen (H).
- Divide by fractional component of each mole value: C=1.5354936431103, H=4.0709872862205Round to closest whole numbers: C=2, H=4
<h3> Combine to get the empirical formula: C2H4</h3>
