Question

10 liter of benzene weight​

Answer 1

Assuming that the conditions are standard conditions of pressure and Temperature( 1atm, 273K)
10L= 10/22.4 moles
10L=0.446moles
Molar mass of Benzene=78
Therefore weight= moles* molar mass
Weight=34.788g

Answer 2

Answer:

mol wt of benzen = 6× 12 + 6× 1 ( h = 1 , c = 12 )

= 72+6=78

at stp 1 mole = 22.4 L

moles in 10L = 10/22.4 = 0.44 mole

if 1 mole = 78g

0.44 mole = 78/.44

= 177.....g
