You need to use the ideal gas equation:
![PV = nRT](https://tex.z-dn.net/?f=PV%20%3D%20nRT)
P is pressure (in atm or bar)
V is volume (in L)
n is the number of moles (in mol)
R is an experimentally determined ratio of about 0.82
T is the temperature (in Kelvin)
Note:
For all gases, you need to convert Celsius or Fahrenheit to Kelvin.![25C + 273.15 = 298.15K](https://tex.z-dn.net/?f=%2025C%20%2B%20273.15%20%3D%20298.15K%20)
Get V alone.
![V = \frac{nRT}{P}](https://tex.z-dn.net/?f=%20V%20%3D%20%5Cfrac%7BnRT%7D%7BP%7D%20)
Plug in the values you have.
![V = \frac{2.50 mol * 0.82 * 298.15 K}{1.49 atm}](https://tex.z-dn.net/?f=%20V%20%3D%20%5Cfrac%7B2.50%20mol%20%2A%200.82%20%2A%20298.15%20K%7D%7B1.49%20atm%7D)
you get:
![V = 611.2075L](https://tex.z-dn.net/?f=%20V%20%3D%20611.2075L%20)
A fun fact: the gas used to fill up a balloon is Helium.
Answer:
B
Explanation:
stronger gravitational gradient
Explanation:
Atomic number = 1
Mass number = 1
Proton = 1
Neutron = mass number - atomic number
= 1 - 1
= 0
