1. Co2 has molar mass =44 mol^-15
moles of co2 has molar mass 44×5 = 220g
but , when we take h2o molar mass=18 g mol^-1
moles of h2o= 18×5=90 g
so , 5 moles of co2 and h2o is not equal 22g is not equal to 90g..
Even second one and third one u want yahh didi...
I hope it helps u didiSorry didi 2 and 3 i tried it but it is not coming didi..
Have a glorious day didi...didi pls make it as a brainlist answer...
ANSWER
Mass of 5 moles of CCO=5× Molecular mass of CO2.
=5×44
=220g ⟶(i)
Mass of 5 moles of H2O=5× Molecular mass of H2O
=5×18
=90g ⟶(ii)
From eqn (i) and (ii), we can conclude that they don't have the same mass.
Difference in their masses= 220−90
130 grams
ANSWER
Given:At. Mass of S = 32 u
Atomic mass of S8 = 8 × 32u = 256u
1 mole of Al atom = 6.022 × 10²³atoms
This means 265g of S8 has 6.022 × 10²³ molecules
Then 64g g contains: Number of S8 molecules=
given mass\molar mass × 6.022 x 10²³
Number of S8 molecules =
64g\266u × 6.022 x 1023
⇒ Number of S8 molecules = 1.5 x 10²³ molecules
Thus, the number of molecules of sulphur (S8) is 1.5 x 10²³ molecules.
ANSWER
Number of molecules(N) = Given mass X Avgadros no / Molar mass
Molar mass of 1 mole of N2= 14 × 2 =28
N = 56/ 28 ×6.022 × 1023 N = 12.044 × 10²³
Hence there are 12.044 × 10²³ particles present in 56 gm of N2
