Question

chapter 11 homework exercise 11.24 - enhanced - with feedback 88.4 psi express your answer in atmospheres to three significant figures. p = atm submit request answer missed this? read section 11.3. you can click on the review link to access the section in your etext. convert each measurement to atm. part d 34.30 in. hg express your answer in atmospheres to four significant figures. p = atm submit request answer

Explanation:

Step1: Recall pressure conversion factors

We know that \( 1\ \text{atm} = 14.696\ \text{psi} \) (for psi to atm conversion) and \( 1\ \text{atm} = 29.92\ \text{in. Hg} \) (for in. Hg to atm conversion).

Step2: Convert 88.4 psi to atm

Use the conversion factor \( \frac{1\ \text{atm}}{14.696\ \text{psi}} \).
\( P = 88.4\ \text{psi} \times \frac{1\ \text{atm}}{14.696\ \text{psi}} \approx 6.015\ \text{atm} \), rounded to three significant figures is \( 6.02\ \text{atm} \).

Step3: Convert 34.30 in. Hg to atm

Use the conversion factor \( \frac{1\ \text{atm}}{29.92\ \text{in. Hg}} \).
\( P = 34.30\ \text{in. Hg} \times \frac{1\ \text{atm}}{29.92\ \text{in. Hg}} \approx 1.146\ \text{atm} \), rounded to four significant figures is \( 1.146\ \text{atm} \).

Answer:

s:
For 88.4 psi: \( \boldsymbol{6.02\ \text{atm}} \)
For 34.30 in. Hg: \( \boldsymbol{1.146\ \text{atm}} \)
