The formula units of Cr(ClO2)3 that are in 6.85 moles of Cr(Clo203 is <u>4.1237 x10^24 formula units</u>
calculation
the formula units are calculated using of Avogadro's law constant
that is according to Avogadro's law 1 mole = 6.02 x10 ^23 formula units
6.85 moles= ? formula units
by cross multiplication.
= ( 6.85 moles x 6.02 x10^23 formula units ) / 1 mole = <u>4.1237 x 10 ^24 formula units</u>
<h3>
The moles of Oxygen contained in 6.85 moles of cr(ClO2)3 is <em><u>
41.1 moles</u></em></h3>
<em><u> </u></em><u><em>calculation</em></u>
<em>moles of oxygen = number of oxygen atom in Cr(ClO2)3 x 6.85(moles of Cr(ClO2)3</em>
calculate the number of oxygen atoms that are in Cr(ClO2)3
that is 2 x 3 = 6 atoms of Oxygen.
moles is therefore = 6 x 6.85 moles= 41.1 moles
