Answer : The correct option is, (C) 0.6 ml

Explanation : Given,

Initial volume of solution in the burette = 32.3 ml

Final volume of solution in the burette = 32.9 ml

As the liquid is colorless. So, we are taking the lower meniscus for the correct reading of the solution.

Now we have to calculate the total volume of solution that was dispensed from this burette.

\text{Total volume of solution dispensed}=\text{Final volume of solution in the burette}-\text{Initial volume of solution in the burette}

Now put all the values in this formula, we get the total volume of solution that was dispensed from this burette.

\text{Total volume of solution dispensed}=32.9ml-32.3ml=0.6ml

Therefore, the the total volume of solution that dispensed from this burette was, 0.6 ml

What is the pH of a solution with a concentration of 1.8 × 10-4 molar H3O+?
Andre45 [30]
PH is defined as the negative log of Hydrogen ion concentration. Mathematically we can write this as:

pH=-log[H^{+}]=-log[H_{3}O]

We are given the concentration of H_{3}O. Using the value in formula, we get:

pH=-log[1.8*10^{-4}]=3.745

Therefore, the pH of the solution will be 3.745

A material has a volume of 63.0 cm3 and a mass of 28 grams.  What is the density of the material in g/cm3 to the correct number
dimaraw [331]

Answer:

0.4444 g/cm³ ≅ 0.44 g/cm³ (2 significant figures).

Explanation:

  • Knowing that:

<em>d = m/V,</em>

where, d is the density of the material (g/cm³).

m is the mass of the material (m = 28 g).

V is the volume of the material (V = 63.0 cm³).

<em>∴ d = m/V </em>= (28 g)/(63.0 cm³) = <em>0.4444 g/cm³ ≅ 0.44 g/cm³ (2 significant figures).</em>

Consider a neutrally charged atom that has an atomic mass number of 80, which includes 35 neutrons. how many electrons does this
ivanzaharov [21]
Atomic mass number is the number of protons and neutrons. Subtract 80-35=45 is the number of protons. Because the atom is neutrally charged, the number of protons must equal the number of electrons, so there are 45 electrons.

Calculate the value of the equilibrium constant, Kc, for the reaction below, if 0.208 moles of sulfur dioxide gas, 0.208 moles o
Harman [31]
First, we convert the moles of each substance into the concentration using the volume of the reactor.
[SO₃] = 0.425/1.5 = 0.283 M
[SO₂] = 0.208 / 1.5 = 0.139 M
[O₂] = 0.208/1.5 = 0.139 M
The equilibrium constant is calculated by:
Kc = [SO₃]² / [O₂][SO₂]²
Kc = (0.283)²/(0.139)(0.139)²
Kc = 29.8 = 2.98 x 10¹

The answer is C
