What is the mass (in grams) of 9.09x10^24 molecules of methanol (CH3OH)?
zloy xaker [14]

The amount of a substance can be converted into grams of that substance by using the molar mass. It is a physical property of a substance which describes the mass per mole of the substance. The molar mass of CH3OH is 32.04 g/ mol. Multiplying the given amount of CH3OH with the molar mass will yield to the mass of the substance.

<span>9.09x10^24 molecules CH3OH ( 1 mol / 6.022x10^23 molecules) (32.04 g/mol) = 483.63 g CH3OH

Dividing the molar mass of N2O which is 44.08 g/mol to the given amount will yield to the number of moles.

0.183 g N2O / 44.08 g/ mol =0.0042 mol N2O</span>

Explain the relationship between monomers and polymers using polysaccharides as an example
Mars2501 [29]

Answer:

Glucose and glycogen.

Explanation:

Hello,

Monomers are the functional molecules forming the polymers when an random amount of units (monomers) are linked form an assembly (polymer).

This could be exposed by considering the glucose as the monomer forming the glycogen which is a polymer that serves as a form of energy storage in animals, fungi, and bacteria; it is constituted by about 30,000 units of both lineal and branched glucose which provide many features that the glucose doesn't have by itself.

Best regards.

How many atoms are present in a sample of Potassium (K) weighing 33.49g?
madam [21]

Answer:

5.158 × 10²³ atoms K

General Formulas and Concepts:

<u>Chemistry - Atomic Structure</u>

  • Reading a Periodic Table
  • Using Dimensional Analysis
  • Avogadro's Number - 6.022 × 10²³ atoms, molecules, formula units, etc.

Explanation:

<u>Step 1: Define</u>

33.49 g K

<u>Step 2: Identify Conversions</u>

Avogadro's Number

Molar Mass of K - 39.10 g/mol

<u>Step 3: Convert</u>

<u />33.49 \ g \ K(\frac{1 \ mol \ K}{39.10 \ g \ K} )(\frac{6.022 \cdot 10^{23} \ atoms \ K}{1 \ mol \ K} ) = 5.15797 × 10²³ atoms K

<u>Step 4: Check</u>

<em>We are given 4 sig figs. Follow sig figs and round.</em>

5.15797 × 10²³ atoms K ≈ 5.158 × 10²³ atoms K
