Answer:

The transmittance is the amount of energy that a body goes through in a certain amount of time without being absorbed and the absorbance is the amount of light that is absorbed by a solution.

There is no difference between absorptivity and molar absorptivity because the two terms express the same idea, because molar absorptivity is the absorbance of a solution per unit path length and concentration, so that the absorbance is proportional to concentration.

What volume will 20.0g of Argon occupy at STP?

Yuki888 [10]

Molar mass Argon = 39.948 g/mol

1 mol ------ 39.948 g
mol ----- 20.0 g

mol = 20.0 * 1 / 39.948

= 0.5006 moles

1 mol --------------------- 22.4 L ( at STP )
0.5006 moles ------------- L

L = 0.5006 * 22.4

= 11.21 L

hope this helps!
