Question

what is the mass of1.204 *10^22 atoms of nitrogen​

Answer 1

Explanation:

So the 3.40⋅1022 helium atoms weigh 0.226 gram .

Answer 2

Answer:

Mass of 6.022 × 10²³ atoms of N=14g

On dividing by 5 on both sides;

Mass of 6.022/5 ×10²³atoms of N=14/5g

Mass of 1.2044×10²³atoms of N=2.8g

On dividing by 10 on both sides:

∴ Mass of 1.2044×10²²atoms of N=0.28g
