There are three naturally occurring isotopes of magnesium: 24
12Mg, 25
12Mg, and 26
12Mg. In
a weird parallel universe, the percentages of
these isotopes are
Magnesium Natural
Isotopes Abundance
24
12Mg / 43.1%
25
12Mg / 19%
26
12Mg / 37.9%

You can assume the masses are equal to the
mass number. Calculate the weight of “naturally” occurring magnesium in this weird
parallel universe.
Answer in units of g/mol. Your answer
must be within ± 0.015%

the answer is 1260

you spend 7 hours in school for 1 school day with 5 school days in 1 school week with 36 school weeks in a school year.

7*5*36= 1260 it's all about multiplying

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.

you need to have a picture of the atom that way we can answer it

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.
