Asubstance contains 23.0 g sodium, 27.0 g aluminum, and 114 g fluorine. how many grams of sodium are there in a 102-g sample of the substance?

Answer : The mass of sodium are there in a 102-g sample of the substance are 14.28 grams.

Explanation: Given,

Mass of sodium = 23.0 g

Mass of aluminum = 27.0 g

Mass of fluorine = 114 g

Total mass of sample = 102 g

Total mass of substance =  Mass of sodium + Mass of aluminum + Mass of fluorine

Total mass of substance = 23.0 + 27.0 + 114 = 164 g

Now we have to calculate the mass fraction of sodium.

Now we have to calculate the mass of sodium are there in a 102-g sample of the substance.

Therefore, the mass of sodium are there in a 102-g sample of the substance are 14.28 grams.
