Answer to Problem 3.39QP

The percent composition by mass of %Sn=78.7677%;%O=21.2322% because of rounding the overall percentage is slightly less 99.9999%.

Explanation of Solution

To determine: The percent composition by mass of Sn and O in SnO2

Percent composition by mass: percent composition by mass of each element present in a compound is known as the compound’s percent composition by mass. The formula is expressed mathematically as follows:

Percentbymassofanelement=n×atomicmassofelementmolecularorformulamassofcompound×100%Wherenisthenumberofatomsoftheelementinamoleculeorformulaunitofthecompound By using the above formula percent composition by mass is calculated as follows:

FormulamassofSnO2=massofSninamu+(2×massofOinamu)=118.710amu+(2×15.9994amu)=(118.710+31.9988)amu=150.7088amu

Percentbymassof%Sn=1×atomicmassSninamumolecularmassofSnO2inamu×100%=118.710amu150.7088amu×100%=78.7677%

Percentbymassof%O=2×atomicmassOinamumolecularmassofSnO2inamu×100%=2×15.9994amu150.7088amu×100%=31.9988amu150.7088amu×100%=21.2322%

The percent composition by mass of %Sn=78.7677%;%O=21.2322% because of rounding the overall percentage is slightly less 99.9999%.

Conclusion

The percent composition by mass of SnO2 was calculated.

percentmassof%Sn=78.7677%

percentmassof%O=21.2322%

30. We will derive the forms of the molecular partition functions for atoms and molecules shortly in class, but the partition function that describes the translational and rotational motion of a homonuclear diatomic molecule is given by Itrans (V,T) = = 2πmkBT h² V grot (T) 4π²IKBT h² Where h is Planck's constant and I is molecular moment of inertia. The overall partition function is qmolec Qtrans qrot. Find the energy, enthalpy, entropy, and Helmholtz free energy for the translational and rotational modes of 1 mole of oxygen molecules and 1 mole of iodine molecules at 50 K and at 300 K and with a volume of 1 m³. Here is some useful data: Moment of inertia: I2 I 7.46 x 10- 45 kg m² 2 O2 I 1.91 x 101 -46 kg m²
