Answer:
= 3.56 atm
Explanation:
Using Boyle's law which states that the volume of a given mass of gas is inversely proportional to the pressure and Charles law states the volume of a given mass of gas is directly proportional to the temperature.
P1/T1 = P2/T2
P1 = 3.1 atm, T1 = 100'C = 100+273 = 373K
T2 = 155'C = 155 + 273 = 428K
3.1/ 373 = P2 / 428
Cross multiply
373 × P2 = 3.1 × 428
373×P2 = 1326.8
Divide both sides by 373
P2 = 1326.8 ÷ 373
P2 = 3.56 atm

Krafla Volcano in Iceland,
Hello!
First, we can assume the density of water to be
1 g/mL, so the volume of water would be
725 mL. The density of Acetic Acid (Pure) is
1,05 g/mL so 8 grams would represent
7,61 mLNow we can apply the following conversion factor to calculate the molarity of the solution, using the molar mass of Acetic Acid:
![[CH_3CO_2H]=\frac{8 g_{CH_3CO_2H} }{725 mL + 7,61 mL}* \frac{1000 mL}{1 L}* \frac{1 mol_{CH_3CO_2H} }{60,05 g_{CH_3CO_2H} }](https://tex.z-dn.net/?f=%5BCH_3CO_2H%5D%3D%5Cfrac%7B8%20g_%7BCH_3CO_2H%7D%20%20%7D%7B725%20mL%20%2B%207%2C61%20mL%7D%2A%20%5Cfrac%7B1000%20mL%7D%7B1%20L%7D%2A%20%5Cfrac%7B1%20mol_%7BCH_3CO_2H%7D%20%7D%7B60%2C05%20g_%7BCH_3CO_2H%7D%20%7D)
![[CH_3CO_2H]=0,1818 M](https://tex.z-dn.net/?f=%5BCH_3CO_2H%5D%3D0%2C1818%20M)
So, the concentration of acetic acid would be
0,1818 MHave a nice day!
