define the following write the units and formula
The answer is actually 4/3, or about 1.333. Calculators usually can only calculate logarithms in base e (2.718...) and in base 10. To calculate in another base, you use the change-of-base formula; in this case: log8(16) = log10(16) / log10(8) Or any other base; for example, using natural logarithms: log8(16) = ln(16) / ln(8)

3MgBr2
In math, that may either refer to changing the base of the number system (for example, change from decimal (base 10) to binary (base 2)); or it may refer to changing logarithms, from one base to another - for example, common (base-10) logarithms to natural (base-e) logarithms.
The formula of sodium carbonate is Na2CO3 and contains the following (elemental) symbols: Na for sodium, C for carbon, O for oxygen.

Formula
For sodium oxide, the empirical formula is the same as the formula unit, Na2O. (If any formula unit or molecular formula contains an atomic symbol with no following subscript, the empirical and actual formulas will be the same.)
To create a thought that is realistic
define the following write the units and formula
sulphur and hydrogen the molecular formula is H2SO4
A formula that contains more than one atom.
The formula is proprietary, but it contains cyclotrimethylenetrinitramine and pentaerythritol tetranitrate.
Er... What chemical formula?
