<h3>Answer:</h3>

0.03192 M

<h3>Explanation:</h3>

We are given;

  • Initial volume before dilution, V1 = 15.0 mL or 0.015 L
  • Volume after dilution, V2 = 125.0 mL or 0.125 L
  • Concentration after dilution, M2 = 0.00383 M

We are required to calculate the initial concentration, M1 before dilution.

  • To answer the question, we will use the dilution formula;
  • Dilution formula is given by; M1V1 = M2V2

Rearranging the formula;

M1 = M2V2 ÷ V1

    = ( 0.00383 M × 0.125 L) ÷ 0.015 L

   = 0.03192 M

Therefore, the original concentration of the solution before dilution is 0.03192 M

Consider the following three samples. A. A sample containing 180 g glucose (C6H12O6) B. A sample containing 90 g glucose and 90
Aloiza [94]

Answer:

E) All three samples have the same number of hydrogen atoms

Explanation:

The statements are:

A) Sample A has more hydrogen atoms than sample B or sample C.

B) Sample B has more hydrogen atoms than sample A or sample C.

C) Sample C has more hydrogen atoms than sample A or sample B

D) Both samples A and C have the same number of hydrogen atoms, but more than in sample B.

E) All three samples have the same number of hydrogen atoms

Hydrogens in sample A are:

180g × (1mol Glucose / 180.156g) × (12mol H / 1 mol Glucose) =<em> 12 moles of H</em>

Hydrogens in sample B are:

90g Glucose × (1mol Glucose / 180.156g) × (12mol H / 1 mol Glucose) =<em> 6 moles of H</em>

90g mannose× (1mol Mannose / 180.156g) × (12mol H / 1 mol Glucose) =<em> 6 moles of H</em>

<em>Total moles: 12</em>

Hydrogens in sample C are:

180g × (1mol Mannose / 180.156g) × (12mol H / 1 mol Glucose) =<em> 12 moles of H</em>

<em />

Thus, right answer is:

<em>E) All three samples have the same number of hydrogen atoms</em>

<em></em>

I hope it helps!
