The volume of NaOH required is 0.08 dm³
To solve this question, we'll begin by writing the balanced equation for the reaction between H₂SO₄ and NaOH. This is illustrated below:
H₂SO₄ + 2NaOH —> Na₂SO₄ + 2H₂O
From the balanced equation above,
Mole ratio of the acid, H₂SO₄ [tex](n_{A}) = 1[/tex]
Mole ratio of the base, NaOH [tex](n_{B}) = 2[/tex]
Next, we shall determine the volume of NaOH required to react with H₂SO₄. This can be obtained as follow:
Molarity of the base, NaOH [tex](M_{B}) = 0.505 M[/tex]
Volume of the acid, H₂SO₄ [tex](V_{A}) = 40 mL[/tex]
Molarity of the acid, H₂SO₄ [tex](M_{A}) = 0.505 M[/tex]
Volume of the base, NaOH [tex](V_{B})[/tex] =?[tex]\frac{M_{A} * V_{A}}{M_{B} * V_{B}} = \frac{n_{A}}{n_{B}}\\\\\frac{0.505 * 40}{0.505 *V_{B}} = \frac{1}{2}\\\\\frac{20.2}{0.505 *V_{B}} = \frac{1}{2}[/tex]
Cross multiply
[tex]0.505 * V_{B} = 20.2 * 2\\0.505 * V_{B} = 40.4[/tex]
Divide both side by 0.505
[tex]V_{B} = \frac{40.4}{0.505}\\\\V_{B} = 80 mL[/tex]
Finally, we shall convert 80 mL to dm³. This can be obtained as follow:
[tex]1000 mL = 1 dm^{3}\\\\Therefore,\\\\80 mL = \frac{80 mL * 1dm^{3}}{1000 mL}\\\\80 mL = 0.08dm^{3}[/tex]
Therefore, the volume of NaOH required is 0.08 dm³

h = 3.0 a + 28.2
A pediatrician uses the model above to estimate the height h of a girl, in inches, in terms of the girl's age a, in years. Based on the model, what is the estimated height of a 2-year-old girl?
Answer:
h = 34.2 in
Explanation:
h = 3.0a + 28.2
h = height of a girl.
a = age of a girl.
h = 3.0a + 28.2
h = 3.0(2) + 28.2
h = 6 + 28.2
h = 34.2
The estimated height of a 2-year-old girl is 34.2 in.

Why do you think the mass of the carbon atom shown is 12 atomic mass units (amu)?
Answer:
The mass of Carbon-12 is exactly 12 amu. But, that is not the number that is reported in your periodic table. Carbon as it exists in nature is not all carbon-12. There is some small amount of carbon-13 and even traces of carbon-14 in there. The periodic table reports the average mass of the carbon as it is found in nature, not that of pure carbon-12. The average mass of carbon is slightly heaver than carbon-12, because of the slight amounts of those heaver isotopes of carbon in nature.

If an object at a distance of 6,400 km from the center of the earth weighs 10N, what will be its weight if it is lifted to 12,800 km from the center of the earth? ion:
Answer:
2.5N
Explanation:
since force is inversely proportional to square of the distance apart. that means the ratio of distance apart. so u have 12800×12800÷(6400××6400)=4/1
so the weight will be reduced to 1/4 of 10N
