Arrange the following in order of increasing masses :(i) 0.1g atom silver
(ii) 0.1 mole of H2SO4
III) 10 to the power of 23 molecules of CO2gas
(iv) 1 gram of carbon
(v) 10 to the power of 23 atom of calcium
(Atomic masses : Ag =108 u ,N=14u ,S=32u ,Ca=40u)
Experts, please solve the question by specific formulae and please solve it only with help of specific formulae. Plzzzzzzzzzz...........
(i) 0.1g atom silver = 0.1 gram
(ii) 0.1 mole of H2SO4
Number of moles = Given mass /molecular mass
0.1 = given mass/98
mass of H2SO4 = 0.1 98 = 9.8 gram
III) 10 to the power of 23 molecules of CO2gas
1 mole of gas = 6.023 x 1023 molecule
Mass of 6.023 x 1023 molecule CO2 gas = 12 +16 +16 = 44 gram
Mass of 1023 molecule of gas = 44/6.023 x 1023 1023 = 7.3 g
(iv) 1 gram of carbon = 1 gram
(v) 10 to the power of 23 atom of calcium
1 mole of atom = 6.023 x 1023 atoms
Mass of 6.023 x 1023 atom of Ca = 40 gram
Mass of 1023 atom of Ca = 40/6.023 x 1023 1023 gram = 6.64 g
Increasing order according to mass:
0.1g atom silver 1 gram of carbon 10 to the power of 23 atom of calcium 10 to the power of 23 molecules of CO2 0.1 mole of H2SO4
