Answer:
Explanation:
Any gas at standard temperature and pressure (STP) has a volume of 22.4 liters per mole or 22.4 L/mol. We can create a proportion with this value.
Multiply both sides of the equation by 6.8 moles of krypton.
The units of moles of krypton will cancel.
The denominator of 1 can be ignored, so this becomes a simple multiplication problem.
If we round to the nearest whole number, the 3 in the tenths place tells us to leave the 2 in the ones place.
6.8 moles of krypton gas at standard temperature and pressure is equal to <u>152 liters</u>.
Answer:
The new pressure in the balloon is 16.3 atm
Explanation:
Gay-Lussac's law establishes the relationship between the temperature and the pressure of a gas when the volume is constant.
This law establishes that pressure and temperature are directly proportional quantities, that is to say that if the temperature increases the pressure increases and if the temperature decreases the pressure decreases.
Mathematically, Gay-Lussac's law states that, when a gas undergoes a constant volume transformation, the quotient of the pressure exerted by the gas temperature remains constant:
When you want to study two different states, an initial one and a final one, of a gas, you can use the expression:
In this case:
- P1= 14.7 atm
- T1= 273 K
- P2= ?
- T2= 303 K
Replacing:
Solving:
P2= 16.3 atm
<u><em>The new pressure in the balloon is 16.3 atm</em></u>
