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.

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.
