Answer 1

Answer:

1.5 mol/ltr

solution--

Active mass is nothing but the molarity term so the same formula applicable here

i. e

molarity = weight of solute ÷[ molar mass× weight of solution in litre ]

m=96g÷[32g/mol×2 ltr]

m=1.5mol/ltr

where the molecular mass of oxygen molecule 32 gram per mole
