To convert the formula units of a compound to its mass, the conversion factor is Avogadro's number, 6.022 x10^23 formula units/ mol and its molar mass. In this case, we are given with 5.30x1022 formula units of Barium nitrate which has a mass of 261.33 g/mol. Hence the answer is 23.00 grams.

Answer:

Mass of [tex]5.30\times 10^{22}[/tex] formula units of [tex]Ba(NO_{3})_{2}[/tex] is 23.0 g

Explanation:

Molar mass of [tex]Ba(NO_{3})_{2}[/tex] is 261.337 g.

So, mass of [tex]6.023\times 10^{23}[/tex] formula units of [tex]Ba(NO_{3})_{2}[/tex] is 261.337 g.

Hence mass of [tex]5.30\times 10^{22}[/tex] formula units of [tex]Ba(NO_{3})_{2}[/tex] is [tex]\frac{261.337\times 5.30\times 10^{22}}{6.023\times 10^{23}}[/tex] g = 23.0 g
