Molar mass is the ratio of the mass to that amount of the substance. The mass of the barium nitrate in the formula unit is 23.0 grams.
<h3>What is mass?</h3>The mass of a substance is the product of the molar mass of the compound and the number of moles of the compound.
Given,
Molar mass of barium nitrate = 261.35 g/mol
If, have a mass of 261.35 g/mol then,
formula units will have a mass of,
Therefore, option C. 23.0 gm is the mass of barium nitrate.
