The approximate total mass= number of atoms * weight of an atom.
The approximate total mass=3.06 10²³ atoms. (1.67 10⁻²⁴ grams/1 atom)=
=0.51102 g ≈ 0.51 g
Answer: the spproximate total mass is 0.51 grams.
If one sound is 10^x times more intense than another sound, then it has a sound level which is 10*x more decibels than the less intense sound. So, 10*6=60=7.75^2≈60
Answer:
6 * 10 to the -2nd power = 0.00027777777
4.2 to the -3rd power = 0.01349746247
