What is the formula of magnesium nitrite?
There 3.23 g of Mg(NO3)2 present.
How do you find the formula mass?
To calculate formula mass, multiply the subscript of each element in the formula by the element’s atomic weight (relative atomic mass) found on the periodic table. The unit for formula mass is either u or Da (Daltons). The amu has been replaced with u, even though it is still commonly used.

What is the formula weight of ethanol?
The formula mass of a molecule (also known as formula weight) is the sum of the atomic weights of the atoms in the empirical formula of the compound. Formula weight is given in atomic mass units (amu).
What is the formula of mass and weight?
Mass = volume × density and Weight = mass × acceleration due to gravity. Weight = volume × density and mass = mass × acceleration due to gravity.
How is atomic weight calculated?
The atomic weight of any atom can be found by multiplying the abundance of an isotope of an element by the atomic mass of the element and then adding the results together. This equation can be used with elements with two or more isotopes: Carbon-12: 0.9889 x 12.0000 = 11.8668.
