The lab technician places 0.97 moles of magnesium into a beaker. How many magnesium atoms are in the beaker?

There are 5.84*10²³ magnesium atoms in the beaker.

Explanation:

Avogadro's Number or Avogadro's Constant is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023*10²³ particles per mole. Avogadro's number applies to any substance.

So, to calculate the amount of magnesium atoms present in the beaker, the following rule of three is applied: if by definition of Avogadro's Number in 1 mole there are 6.023*10²³ atoms, in 0.97 moles how many atoms are there?

atoms=5.84*10²³

There are 5.84*10²³ magnesium atoms in the beaker.

the answer is a. co2, this would be colder than the : )

explanation:

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
