Question

How many moles of helium gas are present in a balloon with a volume of 950 ml a pressure of 3.47 atm and a temperature of 104 degrees celcius

Answer 1

.107 moles

Step-by-step explanation:

To find moles given the info above, we use a variation of the Ideal Gas Law,

mol = PV/RT, where P is in atm, V is in L, T is in K, and R is the gas constant

• P=3.47 atm
• L= .950 L
• T= 377 K
• R= .08206

mol= 3.47(.950) / 377(.08206)

• =.107 moles H2
