Answer 2

1.quick line - quick line is calcium oxide and elements present in it are calcium and bromine

2. one mole of carbon atoms weighs 12g

I.e,mass of 1 mole of carbon atoms=12g

then, mass of 6.022×10^23 no of carbon atoms = 12g

therefore,mass of 1 atom of carbon=12÷6.022×10^23

=1.9926×10^23
