Asked by admin @ in Chemistry viewed by 331 People

Calculate the number of particles in each of the following: (1) 46g of Na atoms (number from mass) (2) 8g O2 molecules (number of molecules from mass) (3) 0.1 mole of carbon atoms (number from given moles) .

Answered by admin @


Explanation:

1st moles=46/23=2

no of particles=mole×Na

=2×6.02×10^23

=12.04×10^23

2nd moles= 8/32=1/4

no of particles=1/4×6.02×10^23

= 1.505×10^23

3rd moles= 0.1 (given)

no of particles= 0.1×6.02×10^23

= 0.602×10^23
