Find the volume of oxygen gas that reacts with 6.8 dm3 of butane (C4H10) gas measured at the same temperature and pressure. 2C4H10(g)+130 2(g)->8CO2(g)+10H20(l)

h let me think

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.

sure im new too!

explanation:

the correct answer to this question is 2
