Which equation agrees with the ideal gas law?
photoshop1234 [79]
<span>\frac{(P1)(V1)}{T1}=\frac{(P2)(V2)}{T2} is directly related to the ideal gas law.

The ideal gas law states that:PV=nRT. Rewriting this gives:\frac{PV}{T}=nR. R is the universal gas constant, so its value is fixed. For a given sample, n is the number of moles of the gas, so its value would be fixed too. This means that the value of \frac{PV}{T} would be a fixed constant as well. Therefore, whatever the initial value \frac{(P1)(V1)}{T1} is, it should be equal to the final value \frac{(P2)(V2)}{T2}.</span>

Determine the empirical formula of a compound containing 40. 6 grams of carbon, 5. 1 grams of hydrogen, and 54. 2 grams of oxyge
zavuch27 [327]

The empirical formula is C₂H₃O₂

<h3>What is Empirical formula of a compound ?</h3>

The empirical formula is the simplest whole number ratio of elements present in a compound.

The total molar mass of the compound is 118.084 g/mol.

mass of Carbon present = 40.6

mass of Hydrogen present = 5.1 grams

mass of Oxygen present = 2 grams

Moles of C = 40.6/12 = 3.38

Moles of H = 5.1/1.008 = 5

Moles of Oxygen = 54.2/15.999 = 3.38

Ratio of Moles of C to Oxygen is 1 : 1

Ratio of Moles of C to H is 1/1.5

Multiplying each mole fraction by 2

The empirical formula is C₂H₃O₂
