Question

Arrange in the increasing order of mass
1) 1g of carbon
2) 12amu of carbon
3)11.2L of N2
4)1 mole water​

Answer 1

Answer:

(1) 1 molecule of oxygen=O2

∴ Mass of O2=NA16×2=NA32g=6.022×102332=5.3×10−23g

(2) 1 atom of Nitrogen=NA1 moles

=6.022×10231 moles

=1.66×10−24moles

∴ Mass of 1 atom of Nitrogen=1.66×10−24×14

=23.2×10−24g

(3) 1×10−10gm molecule  of oxygen=1×10−10 moles of O2

∴ Mass of 1×10−10gm molecule of oxygen=1×10−10×32

=3.2×10−9g

(4) Mass of copper=1×10

Comparing the masses in (1), (2), (3) and (4)

we get, (2)<(1)<(4)<(3)

Therefore, answer is (II)<(I)<(IV)<(III).

i hope my answer is correct any doubt you can ask me thank you
