<u>How to find?</u></h3>
For solving this question, We need to know how to find moles of solution or any substance if a certain weight is given.

<h3>
<u>Solution:</u></h3>
Atomic weight of elements:
Ca = 40
C = 12
O = 16
❍ Molecular weight of 
= 40 + 12 + 3 × 16
= 52 + 48
= 100 g/mol
❍ Given weight: 10 g
Then, no. of moles,
⇛ No. of moles = 10 g / 100 g mol‐¹
⇛ No. of moles = 0.1 moles
☄ No. of moles of Calcium carbonate in that substance = <u>0.1 moles</u>

9.0532e-5 should be correct! hope this helps
<span>1.Which best explains why ionization energy tends to decrease from the top to the bottom of a group?
D.Electrons get farther from the nucleus. </span>They experience a weaker attraction to the positive charge of the nucleus.<span>
3.When electrons are removed from the outermost shell of a calcium atom, the atom becomes
D. a cation that has a smaller radius than the atom. </span><span>Since the atom is losing an electron, it not only becomes positively charged, also the effective nuclear charge diminishes making the remaining electrons aproach the nucleus.</span>
