<h2>9. Given : P + O2 = P2O5</h2>

Balanced Chemical Equation: <u>4</u>P + <u>5</u>O2 = <u>2</u>P2O5

<u>Reactant Product</u>

P = (1) 4 | P = (2) 4

O = (2) 10 | O = (5) 10

Reaction Information

Phosphorus + Dioxygen = <u>Phosphorus Pentoxide</u>

Reaction Type: <u>Synthesis</u>

<h2>10. Given: HCl + NaOH = NaCl + H2O </h2>

<u>Reactant Product</u>

H = 2 | H = 2

Cl = 1 | Cl = 1

Na = 1 | Na = 1

O = 1 | O = 1

<h3>Chemical Equation is already in balance.</h3>

How much of glucose (C6H1206) is needed to make 1 L of a 1-M solution? Use details to support your answer.
Yakvenalex [24]

Answer:

200 g C₆H₁₂O₆

General Formulas and Concepts:

<u>Chemistry - Solutions</u>

  • Reading a Periodic Table
  • Using Dimensional Analysis
  • Molarity = moles of solute / liters of solution

Explanation:

<u>Step 1: Define</u>

1 M C₆H₁₂O₆

1 L of solution

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

Molar Mass of C - 12.01 g/mol

Molar Mass of H - 1.01 g/mol

Molar Mass of O - 16.00 g/mol

Molar mass of C₆H₁₂O₆ - 6(12.01) + 12(1.01) + 6(16.00) = 180.18 g/mol

<u>Step 3: Find moles of solute</u>

1 M C₆H₁₂O₆ = x mol C₆H₁₂O₆ / 1 L

x = 1 mol C₆H₁₂O₆

<u>Step 4: Convert</u>

<u />1 \ mol \ C_6H_{12}O_6(\frac{180.18 \ g \ C_6H_{12}O_6}{1 \ mol \ C_6H_{12}O_6} ) = 180.18 g C₆H₁₂O₆

<u>Step 5: Check</u>

<em>We are given 1 sig figs. Follow sig fig rules and round.</em>

180.18 g C₆H₁₂O₆ ≈ 200 g C₆H₁₂O₆
