1. What is the density, in g/cm², of a substance weighing 22.2 cg with dimensions of 0.333

RUDIKE [14]

Mass=22.2cg=2.22g

Volume:-

$\\ \tt\longmapsto 0.333(0.444)(0.555)=0.08cm^3$

$\\ \tt\longmapsto Density=\dfrac{Mass}{Volume}$

$\\ \tt\longmapsto Density=\dfrac{2.22}{0.08}=27.75g/cm^3$

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>

1.2 × 10²⁴ molecules C₆H₁₂O₆ (glucose)

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

Avogadro's Number

<u>Step 3: Convert</u>

Set up: $\displaystyle 1.2 \cdot 10^{24} \ molecules \ C_6H_{12}O_6(\frac{1 \ mol \ C_6H_{12}O_6}{6.022 \cdot 10^{23} \ molecules \ C_6H_{12}O_6})$
Divide: $\displaystyle 1.99269 \ mol \ C_6H_{12}O_6$

<u>Step 4: Check</u>

<em>Follow sig fig rules and round. We are given 2 sig figs.</em>

1.99269 mol C₆H₁₂O₆ ≈ 2.0 mol C₆H₁₂O₆
