Question

do 42 with explanation

the amount and temperature remains the same, what is pressure in the new container in units of atmospheres [atm]? 42. A container holding 1.5 moles [mol] of oxygen (formula: O2, molecular weight- 32 grams per mole Ig/mol]) at a pressure of 1.5 atmospheres [atm] and a temperature of 310 kelvins [K] is heated to 420 kelvins IK], while maintaining constant amount and volume. What is the new pressure inside the container in units of pascals [Pa]? 43. A spacecraft is equipped with nine sensors, designed to gather data to attempt to is used as part of a chemical analysis process. The chemical reaction proceeds most efficiently at a temperature of 27 degrees Celsius [°C]. The 1.2-gallon [gal] reactor Ps

Explanation / Answer

42)

given

n = 1.5 mole
P1 = 1.5 atm
T1 = 310 K
T2 = 420 K
P2 = ?

for a given amount of gas at constant volume, P/T = constant

P2/T2 = P1/T1

P2 = (T2/T1)*P1

= (420/310)*1.5

= 2.0322 atm

= 2.0322*1.013*10^5

= 2.06*10^5 pa <<<<<<<<<--------Answer
