<h3>Answer:</h3>

12.4 g N₂O₂

<h3>General Formulas and Concepts:</h3>

<u>Chemistry</u>

<u>Atomic Structure</u>

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

<u>Stoichiometry</u>

  • Using Dimensional Analysis
<h3>Explanation:</h3>

<u>Step 1: Define</u>

[Given] 1.24 × 10²³ molecules N₂O₂

[Solve] grams N₂O₂

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

Avogadro's Number

[PT] Molar Mass of N - 14.01 g/mol

[PT] Molar Mass of O - 16.00 g/mol

Molar Mass of N₂O₂ - 2(14.01) + 2(16.00) = 60.02 g/mol

<u>Step 3: Convert</u>

  1. [DA] Set up:                                                                                                        \displaystyle 1.24 \cdot 10^{23} \ molecules \ N_2O_2(\frac{1 \ mol \ N_2O_2}{6.022 \cdot 10^{23} \ molecules \ N_2O_2})(\frac{60.02 \ g \ N_2O_2}{1 \ mol \ N_2O_2})
  2. [DA] Divide/Multiply [Cancel out units]:                                                          \displaystyle 12.3588 \ g \ N_2O_2

<u>Step 4: Check</u>

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

12.3588 g N₂O₂ ≈ 12.4 g N₂O₂

Diano4ka-milaya [45]

Answer:

Density=mass / volume.

0.75= mass / 120.

mass= 0.75×120.

mass=90g

Hydroelectricity and tidal energy are similar because
vovikov84 [41]

C.  both sources of energy rely on water.

Explanation:

Hydroelectricity and tidal energy are similar energy sources because they both rely on water.

They harness the power of moving water to produce their energy.

  • Tidal energy is the energy derived from moving water as crashing waves in an ocean.
  • Hydroelectricity is produce when water from a dam channel is used to drive heavy turbines.
  • They are both renewable energy sources.
