Hello There!
We will have water (H2O)
So if you drink a glass of water, you drink a glass of H2O.
Hope it helps! :)
here to help you :)
Answer:
9.15 atm
Explanation:
Ideal gas equation of state PV=nRT
P in hPa, V in L, n in mol, R is a constant which is 83.1 hpa*L/mol*k, T in kelvin.
Plug in all the number, and we will get:
P*6.21=2.02*83.1*343
P =9271.6(in hpa)=9.15 atm
In order to determine the mass of a substance given the volume, we require the density. The density of iron is 7.87 grams/cm³
Now,
Density = mass / volume
Mass = density * volume
Mass = 7.87 * 4.6
36.2 grams of iron are present in the cube
Protons/Electrons: 92
Neutrons: 140
***REMEMBER: There is always the same amount of protons and electrons. :)
