Plz solve q 7 nd q8
Q7. Find the total number fo nucleons present in 12 g of 12C atoms. (12 × 6.022 × 1023)
Q8. Find (i) the total number of neutrons, and (ii) the total mass of neutrons in 7 mg of 14C. (Assume that the mass of a neutron = mass of a hydrogen atom)
[ Hint : 1 14C atom contains 8 neutrons.]
(24.088 ×1020 0.004 g)
No of moles of carbon atoms = 12 g/12g/mole = 1 mole
We know that, Number of atoms = number of moles x Avogadro number
= 1 x 6.022 x 1023 = 6.022 x 1023 In 1 atom of carbon there are 6 protons and 6 neutrons = 12 nucleons.
The number of nucleons = 6.022 x 1023 x 12
for remaining one please ask in separete thread.
