A 2.35 L container of H2(g) at 762 mmHg and 24°C is connected to a 3.17 L container of He(g) at 728 mmHg and 24°C. After mixing, what is the total gas pressure, in millimeters of mercury, with the temperature remaining at 24°C?

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

10

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

6

will have a gram-molecular weight of 352g.

your answer would be “dry”

there is none because earth is stationary and flat.

diaria maybe go see a doctor about that
