The molecular formula of the compound which has a molecular weight of 112.124 atomic mass units is C₆H₈O₂.
<h3>What is molecular formula?</h3>
Molecular formula of any compound tells about the composition and numbers of each entities present in that molecule.
Steps involved in the prediction of molecular formula:
- First we predict the molar mass of given emperical formula as:
Molar mass of C₃H₄O = 3(12) + 4(1) + 16 = 56
- Now we divide the given mass by the calculated mass of empirical formula:
112.124/56 = 2
- Now we multiply the subscripts of given empirical formula by this whole number and we get:
Molecular formula = (C₃H₄O)₂ = C₆H₈O₂
Hence correct option is (E).

Answer:
We have 1.69 moles of gas inside the balloon
Explanation:
Step 1: Data given
Volume of the balloon = 18.9 L
Temperature = 27.1 °C = 300.25 K
Pressure in the balloon = 2.20 atm
Step 2: Calculate the number of moles
p*V = n*R*T
n= (p*V)/(R*T)
⇒with n = the number of moles of gas
⇒with p = the pressure of gas = 2.20 atm
⇒with V = the volume of the gas = 18.9 L
⇒with R = the gas constant = 0.08206 L*atm/mol*K
⇒with T = the temperature = 27.1 °C = 300.25 K
n = (2.20 * 18.9) / ( 0.08206*300.25)
n = 1.69moles
We have 1.69 moles of gas inside the balloon
