The average waist size for teenage males is 29 inches with a standard deviation of 1. 4 inch. If waist sizes are normally distri
sweet [91]

Using the normal distribution, it is found that 0.0764 = 7.64% of teenagers who will have waist sizes greater than 31 inches.

<h3>Normal Probability Distribution</h3>

In a normal distribution with mean \mu and standard deviation \sigma, the z-score of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

  • It measures how many standard deviations the measure is from the mean.
  • After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.

In this problem:

  • The mean is of \mu = 29.
  • The standard deviation is of \sigma = 1.4.

The proportion of teenagers who will have waist sizes greater than 31 inches is <u>1 subtracted by the p-value of Z when X = 31</u>, hence:

Z = \frac{X - \mu}{\sigma}

Z = \frac{31 - 29}{1.4}

Z = 1.43

Z = 1.43 has a p-value of 0.9236.

1 - 0.9236 = 0.0764.

0.0764 = 7.64% of teenagers who will have waist sizes greater than 31 inches.

The vapor pressure of pure acetone (propanone) is 266 torr. When a non-volatile solute is added, the vapor pressure of acetone a
kondaur [170]

The mole fraction of the non-volatile solute in the solution is 0.13.

<h3>Mole fraction of solute </h3>

Using law of vapor pressure formula

Mole fraction of the non-volatile solute=Vapor pressure of the pure acetone-Vapor pressure of the solution /Vapor pressure of the pure acetone

Where:

Vapor pressure of the pure solvent (acetone) =266 torr

Vapor pressure of the solution =232torr

Mole fraction of solute = ?

Let plug in the formula

Mole fraction of the non-volatile solute=266-232/266

Mole fraction of the non-volatile solute=34/266

Mole fraction of the non-volatile solute=0.127

Mole fraction of the non-volatile solute=0.13 (Approximately)

Inconclusion the mole fraction of the non-volatile solute in the solution is 0.13.
