Molecular mass of SO3 = 80.066g /mol
Now for (5.47 × 10 ^1)g of SO3 number of moles = 54.7g/80.066g/mol
Thus number of molecule = number of moles × Avogadro Number
= 0.683 × 6.022 × 1023
= 4.11 × 1023 molecules
Calculate the number of molecules in (5.47x10^1) grams of sulfur trioxide, SO3. Provide your answer to...
A sample of sulfur trioxide (SO3) weighs 5100g. How many molecules are contained in this sample? Use 80.063 the molar mass of SO3. Use 6.022 x 1023 mol-1 for Avogadro's number. Report your answer in scientific notation.Your answer should have two significant figures.
Sulfur dioxide reacts with carbon dioxide to form an equilibrium with sulfur trioxide and carbon monoxide, all gases (see the reaction below). A mixture of 1.81 mole each of sulfur dioxide and carbon dioxide is placed in an 2.1 L container and allowed to reach equilibrium. If the equilibrium constant, Kc, is 1.21 at this temperature, what is the concentration of sulfur trioxide at equilibrium? SO2 (g) + CO2 (g) ⇌ SO3 (2)+ CO (g) Keep extra significant figures during the calculation and...
