A bottle containing 3,587µg of methyl mercaptan (MW=48.1) is accidentally dropped in lab 10ft x 12ft x 8ft. How many ppm will the room contain? Mg/M3 x 24.45 = ppm x MW ppm = (Mg/M3 x 24.45)/MW 1 M3 = 35.315ft3 1Mg = 1000µg

43.452

step-by-step explanation:

284 times .153 = 43.452

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.
