Question

Arrange the following in increasing order: a).1g atom of silver b).1 mole of H2so4 c)10^23 molecules of carbondioxide d)1g of carbon e)10^23 atoms of calcium

Answer 1

Answer:

I know that relative atomic mass of 12C is 12 u.

Therefore mass of 1 mol C=12 g

mass of 6.022⋅1023 C atomsmass of 1 C atom=12 g=12 g6.022⋅1023=1.99⋅10−23 g,

but

1 u⟹Mass of 1 12C atom=1.66⋅10−24 g=1.66⋅12⋅10−24 g=19.92⋅10−24 g=1.992⋅10−23 g.

Which is correct?

Also what is dimension formula of relative atomic mass, molar mass?

Why is unit of molar mass grammole and not just gram Since when has this mol become a unit? It's just a number.
