Question

Weight of 10^22 atoms of carbon

Answer 1

heyy dude

here is your answer

no. of moles = no. of atoms ÷ avagadro number

no. of moles = 10 ki power 22 ÷ 6.022×10 ki power 23

no. of moles = 0.166

no. of moles = given mass ÷ actual mass

0.166 = given mass ÷ 12

0.166×12 =given mass

1.992 is the answer

Answer 2

Weight of 6.022*10^22 atoms of carbon = 12 g

So, weight of 10^22 atoms of carbon= 12*10^22/6.022*10^23

=12*1000/6022

=1.9926g

=1.99g
