5 g of potassium oxalate react to produce 0.03 moles of calcium oxalate.
Calcium oxalate (CaC₂O₄) is obtained by the reaction of 5 g of potassium oxalate (K₂C₂O₄).
We can calculate the moles of CaC₂O₄ obtained considering the following relationships.
- The molar mass of K₂C₂O₄ is 184.24 g/mol.
- The mole ratio of K₂C₂O₄ to CaC₂O₄ is 2:1.

You can cross multiply, it will be easy
There are four quantum numbers: the n, l, m and ms. When the orbital is 2p, it means that n=2 and l = 1. The n number takes the whole number before the sub-orbitals. Then, the designation for the p orbital is l=1. Now, the possible values if m is a range from -l to l. H<em>ence, in this case, that would be: -1, 0, 1.</em>
