Question

1. The volatile organic compound geraniol, a component of oil of roses, is used in perfumery. The density of the vapor at 533K and 0.136 atm is 0.480 g/L. What is the molar mass of geraniol? 5 points) 2. How many grams of CO, (44.0 g/mol) would occupy an 8.8 L flask at 300. K. and 1.1 atm? (5 points) 3. Air bags infiate during collisions because of the decomposition of sodium azide, NaN,. Given the balanced equation for this reaction, what mass (in g) of NaN, (64.99 gmol) is required to infate a 15.0-L air bag to a 2NaNs(s) 2Na(s) + 3Ndg) (5 point

Explanation / Answer

1)
P = 0.136 atm
T = 533 K
density = 0.480 g/L
Lets derive the equation to be used
use:
p*V=n*R*T
p*V=(mass/molar mass)*R*T
p*molar mass=(mass/V)*R*T
p*molar mass=density*R*T

Put Values:
0.136 atm * MM = density * 0.0821 atm.L/mol.K *533.0 K
MM = 154 g/mol

Answer: 154 g/mol
