Answer:
Answer in explanation
Explanation:
Gases are expected to behave as ideal gases at particular temperature and pressure know as the S.T.P.
At a temperature of 273k and a pressure of 1atm, it is expected that a mole of a gas will occupy a volume of 22.4L. Now, a particular student measured the pressure of a gas at 425K, it is expected that the pressure is different from the one that is supposed to be observed at STP and thus , the measures quite differently
The mass of water that will be needed to make the solution is calculated as below
% solution = mass of the solute/mass of the solvent(water) x100
% solution = 5% = 5/100
mass of the solute =0.377 g
mass of the solvent = ?
let the mass of the solvent be represented by Y
= 5/100 =0.377/y
by cross multiplication
5y= 37.7
divide both side by 5
y =7.54 grams
When discussing discordant and harmonious sound waves, the statement tat is false is : if the original waves combine to form irregular displacement of air, the sound will be discordant. The fact is, irregular displacement of air does not guarantee sound discordance
