Use the rule of 3 simple
50 g mean 100% 0,1895 mean x% cross multiplie and calcule the x value x = 0,1895*100/50 = ?%
2mg(s)+02(g)=2mg0 that was the correct answer
V(NaOH)=15 mL =0.015 L
C(NaOH)=0.1 mol/L
C(H₂SO₄)=0.05 mol/L
2NaOH + H₂SO₄ = Na₂SO₄ + 2H₂O
n(NaOH)=V(NaOH)C(NaOH)=2n(H₂SO₄)
n(H₂SO₄)=V(H₂SO₄)C(H₂SO₄)
V(NaOH)C(NaOH)=2V(H₂SO₄)C(H₂SO₄)
V(H₂SO₄)=V(NaOH)C(NaOH)/{2C(H₂SO₄)}
V(H₂SO₄)=0.015*0.1/{2*0.05}=0.015 L = 15 mL
The chemical formula is
composed of hydrogen and oxygen where the two atoms are bonded through hydrogen
bond type of bonding. In this pair, the oxygen is the more electronegative atom
hence the electrons are more directed to it. Because of this, this creates
electron polarity which affects the chemical property of water.

Answer and explanation:
Initially, the pH of the solution will be determined by the dissociation of the weak acid.
Usually, this kind of solution consists of a mixture of weak acid that has not yet reacted and the salt that will be formed by the reaction of the weak acid with a strong base that has been added.
After the dissociation process, the pH will be more affected due to the excess of base in the solution.
