WebWhen 6.384 grams of a hydrocarbon, C x H y , were burned in a combustion analysis apparatus, 21.58 grams of CO 2 and 4.419 grams of H 2 O were produced. In a separate experiment, the molar mass of the compound was found to be 78.11 g / mol. Determine the empirical formula and the molecular formula of the hydrocarbon. WebTo determine the grams to moles for stoichiometry, you still need to use the molar ratio from a balanced equation, but now you need to add in a conversion from grams to moles before using the molar ratio. When you read the question, the given will be in grams, but the unknown will still be in moles.

WebGrams to Moles Conversion Formula Questions: 1. How many moles are in 75.37 grams of sodium chloride, NaCl? Answer: First, find the molar mass of NaCl. Use the periodic … WebA mole of 12 C weighs 12 g (its molar mass is 12 g/mol). This relationship holds for all elements, since their atomic masses are measured relative to that of the amu-reference substance, 12 C. Extending this principle, the molar mass of a compound in grams is likewise numerically equivalent to its formula mass in amu . im gonna go down the slide now
