How many atoms are there in 2.43 g of mercury?

Chemistry
1 answer:
ArbitrLikvidat [17]3 years ago
8 0
Number of moles of mercury = \frac{weight of mercury}{molar mass of mercury} =  \frac{2.43}{200.59} = 0.012 moles. Number of atoms = moles of Hg x 6.02 x 10^23 = 0.012 x 6.02 x 10^23 = 7.224 x 10^21 atoms. Hope this helps!
