50 pts/brainliest calculate the weighted average atomic mass of a sample of sulfer atoms, if 65% of the atoms are the s-32 isotope, 25% of the atoms are the s-31 isotope, and 10% of the atoms are the s-30 isotope.

The average mass of all of

the isotopes of a substance Isotopes are atoms from

the same element

(therefore containing the

same number of protons)

which have different

numbers of neutrons.

1. Multiply the mass of each

isotope by the % of the

isotope

2. Add the products

Sulfur has three main isotopes.

95% is Sulfur-32, 4% is Sulfur-34,

and 1% is Sulfur

- 33.

So 32.09 amu

bonds break, and new bonds form.

the answer is true.
