Answer: 6.022x10²³ (Avogadro's Number)
Explanation: The number of particles in 1 mole of a substance is determined by the Avogadro's Number.
Answer:
0.425M NaOH assuming the volume of KHP was 25.50mL and the volume of the NaOH solution was 30.0mL
Explanation:
The KHP reacts with NaOH as follows:
KHP + NaOH → KNaP + H₂O
<em>Where 1 mole of KHP reacts per mole of KNaP</em>
<em />
That means, the moles of KHP added to the NaOH solution = Moles NaOH at equivalence point. With the moles of NaOH and the volume in liters we can find the molar concentration of NaOH.
<em>Assuming the volume added of KHP was 25.50mL and the solution of NaOH contains 30.0mL (0.0300L), the concentration of the NaOH is:</em>
<em />
<em>Moles KHP = Moles NaOH:</em>
25.50mL = 0.02550L * (0.500mol / L) = 0.01275 moles KHP = Moles NaOH
<em>Molarity NaOH:</em>
0.01275 moles NaOH / 0.0300L =
<h3>0.425M NaOH assuming the volume of KHP was 25.50mL and the volume of the NaOH solution was 30.0mL</h3>
The diagram that show the correct electron configuration is the second option. ⬆⬇1s, ⬆⬇2s, ⬆⬆⬆2p.
<h3>What is electronic configuration?</h3>
The electronic configuration is the representation of electron present indifferent energy levels is an atom. The different type of orbitals are s, p, d, and f.
Thus, the correct option is 2, ⬆⬇1s, ⬆⬇2s, ⬆⬆⬆2p.

I can only think of four and i dont even know if these are correct but milk, cheese, ice cream, and yogurt sorry if i'm incorrect
Molar mass :
O2 = 31.99 g/mol
C5H12 = 72.14 g/mol
<span>C5H12 + 8 O2 = 5 CO2 + 6 H2O
</span>
74.14 g ----------------- 8 x 31.99 g
18 g -------------------- ? ( mass of O2)
18 x 8 x 31.99 / 74.14 =
4606.56 / 74.14 => 62.133 g of O2
hope this helps!
