Question

the number of atoms in 12 grams of carbon -12 is atoms.(given :atomic mass of carbon =12u)​

Answer 1

Answer:

1. As the mass of Carbon-12 in 1g is 12u, it is just simple algebra to calculate the mass of 12 g of C-12

2. The equation is 1g = 12u

3. That implies 12(1g) = 12(12u)

4. Therefore, the answer is 12g = 144u
