Question

if you take 5 moles of carbon atoms in a container and your friend take 5 moles of sodium atoms In another container of same weight whose container has more number of atoms​

Answer 1

Answer:

a) 1 mole = molar mass of a substance.

∴ 1 mole of carbon atoms weigh = 12g

∴5 moles of carbon atoms will weigh = 12 x 5 = 60 g

Hence, Raunak’s container has weigh = 60 g In the same way,

∴ 1 mole of sodium atoms weigh = 23g

∴ 5 moles of sodium atoms will weigh = 23 x 5 = 115 g

Hence, Krish’s container has weigh = 115 g

Thus, Krish’s container is heavier than Raunak’s container.

As, 1 mole = 6.022 x 1023 atoms

(b)Here, both containers have 5 moles of each carbon and sodium, therefore, both containers have equal number of atoms, e., 5 x 6.022 x 1023 atoms,

or 3.011 x 1024 atoms in each.
