How many grams of P3O9 contain 9.67x10^23 atoms of oxygen?​

49.1 g

Explanation:

First we convert 9.67x10²³ atoms of oxygen into moles, using Avogadro's number:

Then we calculate how many P₃O₉ moles there would be with 1.60 O moles:

Finally we convert 0.18 P₃O₉ moles into grams, using its molar mass:

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
