To Find :
Gas’s temperature in Celsius when it has a volume of 25 L, 203 mol, 143.5 atm .
Solution :
We know, by ideal gas equation :
Here, R is universal gas constant and
Putting all given values and R in above equation, we get :
Hence, this is the required solution.
2.7 x 10^24, since 4.5 has two significant figures.
Answer:
solid at room temperature (with the exception of mercury)
usually shiny.
high melting point.
good conductor of heat.
good conductor of electricity.
low ionization energies.
low electro-negativities.
malleable – able to be pounded into sheets.
Answer:
Then pressure will double
Explanation:
PV = nRT
P = nRT / V
If all other variables are kept constant, P will be proportional to n i.e
P1 / n1 = P2 / n2
n = 1
P1 = P
n2 = 2
P2 =?
P1 / n1 = P2 / n2
P /1 = P2/2
Cross multiply
P2 = 2P
Therefore, if an additional 1mole of the gas is added, the pressure will double
