The atomic number or the number of protons in an atom
Answer:
π = 29.3 atm
Explanation:
The osmotic pressure π is given by
π = i MRT, where i=Vant Hoff factor =2 for NaCl ( 2 moles ions/mol NacL)
M = molarity
R = 0.0821 Latm/molK
T = temperature K
Assuming density of solution is 1 g/mL
M= 35 g/58.44 gmol / 1 L = 0.60 M
π = 2.0 x 0.60 mol/L x 0.0821 Latm/kmol x 300K = 29.3 atm
Answer : The amount of codeine in one teaspoonful is, 30 mg
Explanation : Given,
Amount of codeine per fluid ounce = 60 mg
Now we have to determine the amount of codeine present in one teaspoonful.
As we know that:
1 teaspoonful = 0.5 fluid ounce
As, the amount of codeine per fluid ounce = 60 mg
So, the amount of codeine 0.5 fluid ounce =
Thus, the amount of codeine in one teaspoonful is, 30 mg
Answer:
I believe it's the 2nd answer.
Explanation:
Answer:
Kinetic energies of all the gases are same.
Explanation:
The average kinetic energy of molecules of a gas is given by the formula:
K.E = (3/2)KT
where,
K.E = Average Kinetic Energy of the molecule
K = Boltzman's Constant = 1.38 x 10^-23 J/K
T = Absolute temperature of gas
Since, all the gases are in a mixture, and the temperature of the gases must be same and equal to the temperature of mixture.
Therefore, all the terms in the formula are constant and the <u>Average Kinetic Eenergies of all the gases in the mixture (namely, Neon Ne, Krypton Kr, Radon Rn), equal.</u>
