Show the empirical formula manganese fluoride; 59.1% mn and 40.9% f. fill in the subscripts on the formula below. make sure to have a whole number of each subscript, even if it is a 1.

Answer :  The empirical formula of manganese fluoride is .

Solution :  Given,

If percentage are given then we are taking total mass is 100 grams.

So, the mass of each element is equal to the percentage given.

Mass of Mn = 59.1 g

Mass of F = 40.9 g

Molar mass of Mn = 54.94 g/mole

Molar mass of F = 18.99 g/mole

Step 1 : convert given masses into moles.

Moles of Mn = = = 1.076 moles

Moles of F = = = 2.154 moles

Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.

For Mn = 1.076/1.076 = 1

For F = 2.154/1.076 ≈ 2

Mn : F = 1 : 2 

The mole ratio of the element is represented by subscripts in empirical formula.

Therefore, the Empirical formula =

the law of conservation of mass states that in a chemical reaction, the total mass of reactants is equal to the total mass of products. because atoms are only rearranged in a chemical reaction, there must be the same number of sodium atoms and chlorine atoms in both the reactants and products

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
