How many oxygen atoms are in 0.25 calcium nitrate

The question is Incomplete.

How many oxygen atoms are in 0.25 mol calcium nitrate?

-

9.0345 x 10^23

Explanation:-

The chemical formula for Calcium Nitrate is Ca(NO3)2

From the formula we find there are a total of 3 x 2 = 6 Oxygen O atoms in 1 molecule of Calcium nitrate.

We know from Avogadro's Law that 1 mol of a compound has 6.023 x 10^ 23 molecules.

Number of moles of calcium nitrate = 0.25

Number of molecules of Ca(NO3)2 = 0.25 x 6.023 x 10^23

= 1.5075 x 10^23

Number of atoms of O = 6 x 1.5075 x 10^23

= 9.0345 x 10^23

cytokinesis is the splitting of a cell membrane to form 2 identical daughter cells. it's similar to mitosis as both cells have identical copies of dna and cytokinesis is a step in the mitotic cycle.
