The sum of protons and neutrons in an atomic nucleus would be the MASS NUMBER.
Answer:
0.404 moles Na⁺ and 0.404 moles Cl⁻
Explanation:
In the solution you have 23.6g of NaCl. As molar mass of NaCl is 58.44g/mol. Moles you have present are:
23.6g NaCl × (1mol / 58.44g) = <em>0.404 moles of NaCl</em>
As you can see in the formula, each mole of NaCl contains 1 mole of Na⁺ and 1 mole of Cl⁻. Thus, moles of each ion are:
<em>0.404 moles Na⁺ and 0.404 moles Cl⁻</em>
Answer:
d
Explanation:
HF gives its H to HPO42 making it H2PO4, so HF is the acid and F- is the conj base
