Question

if the relative mass of helium is taken as one unit what is that of magnesium​

Answer 1

Answer:

may be the mass of magnesium is six units

Answer 2

Answer:

If the relative mass of Helium is taken as one unit what is that of Magnesium​ will be 6.

Explanation:

Relative masses of He and Mg are respectively 4 and 24. Compared to He as 1, that of Mg is $\frac{24}{4}$ = 6.

How can you determine magnesium's relative atomic mass?

By multiplying the isotope abundance by the isotope mass for each isotope of that element and summing the results, one can get the relative atomic mass. The mass number of an isotope is frequently used in place of the mass to make computations easier.

Magnesium is the lightest of all the metal elements, and because of its strength, corrosion resistance, and lightweight, it is largely utilized in structural alloys. Magnesium is the eighth most common element in the earth's crust, and over 60 different minerals have been found to have 20 percent or more of it.

Thus, Magnesium has a density of 1.738 g/mL, which indicates it will float on water but is still quite light.
