I know the answer it is...
Answer:
52 amu
Explanation:
To get the relative atomic mass of the element, we need to take into consideration, the atomic masses of the different isotopes and their relative abundances. We simply multiply the percentages with the masses. This can be obtained as follows:
[89/100 * 52] + [8/100 * 49] + [3/100 * 50]
46.28 + 3.92 + 1.5 =51.7 amu
The approximate atomic mass of element x is 52 amu
Answer:
in the presence of water, a strong acid will dissociate quickly and release heat, so it is an exothermic reaction.
Explanation:
Answer:
the price for a liter of gas will be of $ 0.3432
Explanation:
⇒ $ gas / L = $ 1.299 / Gal * ( Gal / 3.785 L )
⇒ $ gas / L = $ 0.3432 / L
