Answer:
Empirical formulas can be determined from the percent composition of a compound. In order to determine its molecular formula, it is necessary to know the molar mass of the compound. Chemists use an instrument called a mass spectrometer to determine the molar mass of compounds.
hope this helps :3
I would guess A or B so yeah
Answer:
m = 57.581 g
Explanation:
The actual yield or experimental yield of a reaction is always calculated using the theorical yield and the experimental, using the following expression:
%yield = Exp yield/theo yield * 100 (1)
If we know the theorical yield and the percent of yield, we can calculate the experimental or actual yield by solving the expression above:
Exp yield = %yield * theo yield/100
Replacing the values we have:
Exp yield = 81.1 * 71 / 100
Exp yield = 57.581 g
And this would be the actual yield of the reaction
Answer:
I'd say the answer is Clustered (Based on the image)
