Answer:
ethier a dessert or a plains
though plains can get rain in the summer
from me living in both
it seems more like a dessert
To calculate the molarity you only need to know the number of moles in the solution and the volume of that solution. This exercise gives both and with that you divide moles by volume(usually in liters).
500 ml equals 0,5 L
molarity= number of moles/ volume
molarity=0,75 x 0,5
= 0,375 mol/L
0.091 moles are contained in 2.0 L of N2 at standard temperature and pressure.
Explanation:
Data given:
volume of the nitrogen gas = 2 litres
Standard temperature = 273 K
Standard pressure = 1 atm
number of moles =?
R (gas constant) = 0.08201 L atm/mole K
Assuming nitrogen to be an ideal gas at STP, we will use Ideal Gas law
PV = nRT
rearranging the equation to calculate number of moles:
PV = nRT
n =
putting the values in the equation:
n =
n = 0.091 moles
0.091 moles of nitrogen gas is contained in a container at STP.
Answer:
( A ) Increases
Explanation:
More room, basically means more creatures. Like in a bedroom, you can only fit amount of people if its small the ocean is like that with depth.
Hopefully this makes sense???
