Answer is: <span>the molarity of the diluted solution 0,043 M.
</span>V(NaOH) = 75 mL ÷ 1000 mL/L = 0,075 L.
c(NaOH) = 0,315 M = 0,315 mol/L.
n(NaOH) = c(NaOH) · V(NaOH).
n(NaOH) = 0,075 L · 0,315 mol/L.
n(NaOH) = 0,023625 mol.
V(solution) = 0,475 L + 0,75 L.
c(solution) = 0,023625 mol ÷ 0,550 L.
c(solution) = 0,043 mol/L.
Answer:
The answer to your question is: 98 gr / mole
Explanation:
Molecular weight and molecular mass are synonyms and they referred to sum of the the molecular masses of the elements that form part of a compound. Their units are grams/ mole
In your example we need to sum the molecular mass of the components of sulphuric acid.
Like this:
Hydrogen(H) = 1.008 x 2
Sulphur (S) = 32 x 1 = 32
Oxygen = 16 x 4 = 64
Total = 98 gr / mole
