Answer 2

Mass of one nucleon=1.66×10^-24kg

Question 3

AM=

Answer 3

RAM×1 amu

Question 4

Azide and nitride???

Answer 4

N3- and N³-

Question 5

KB5

Answer 5

Sample ke mass se sample ka moles

Sample ke moles se atom ke moles

Atom ke moles se atom ka. Mass

Question 6

Sp gty?

Answer 6

Density of substance / densitybof water at 4⁰C i.e. 1g/ml

Question 7

Rel density pf gas 1 wrt gas 2

Answer 7

P1M1T2/P2M2T1

Under sinilar conditions: T2/T1

Question 8

Vapor density?

Answer 8

Density of substance (gas or vapor phase)/density of H2 gas under similar conditions

=M/2

Question 9

Kb1

Answer 9

Grm hatao Na lagao nucleons le jao

Irrespective of the name of the sample if weights are same the number of nucleons are same

Question 10

Avogadro’s hypothesis

Answer 10

Equal volumes of all gases have equal number of molecules not atoms at same temperature and pressure

V is directly proportional to N at constant temperature in pressure

Question 11

Y map

Answer 11

See in notebook

Question 12

Kb 6

Answer 12

Irrespective of the weight of the sample the percentage of individual individual element in a compound always remain same but weight of individual elements may differ
