Answer:

1.10 × 10⁻¹² m

General Formulas and Concepts:

<u>Chemistry - Atomic Structure</u>

Speed of Light = Wavelength times Frequency

  • c = λν
  • c = 3.0 × 10⁸ m/s

Explanation:

<u>Step 1: Define</u>

ν  = 2.73 × 10²⁰ Hz

<u>Step 2: Find wavelength</u>

3.0 × 10⁸ m/s = λ(2.73 × 10²⁰ Hz)

λ = 1.0989 × 10⁻¹² m

<u>Step 3: Check</u>

<em>We are given 3 sig figs. Follow sig fig rules.</em>

1.0989 × 10⁻¹² m ≈ 1.10 × 10⁻¹² m

Enough of a monoprotic weak acid is dissolved in water to produce a 0.0118 M solution. The pH of the resulting solution is 2.32
ser-zykov [4K]

Answer:

1.94 × 10⁻³

Explanation:

Step 1: Calculate the concentration of H⁺ ions

We will use the definition of pH.

pH = -log [H⁺]

[H⁺] = antilog -pH = antilog -2.32 = 4.79 × 10⁻³ M

Step 2: Calculate the acid dissociation constant (Ka) of the acid

For a monoprotic weak acid, whose concentration (Ca) is 0.0118 M, we can use the following expression.

Ka = [H⁺]²/Ca

Ka = (4.79 × 10⁻³)²/0.0118 = 1.94 × 10⁻³

A mole represents a macroscopic quantity of matter that can be used in the laboratory.
KonstantinChe [14]

Answer:

A. True

Explanation:

Mole is the unit associated with measuring substances in chemistry. Chemicals are usually measured in moles and it is derived from the formula - mass/molar mass.

This makes the mole a definition of the representation of a macroscopic quantity of matter that can be used in the laboratory and hereby validates the answer as being true .
