What is the mole ratio of H2O to C8H8?
zepelin [54]

Answer:

Mole ratio for a compound

The chemical formula tells us the mole ratio.

CO2 = 1 CO2 molecule : 1 C atom : 2 O atoms.

Mole ratio for a reaction

The balanced chemical reactions tells us.

C12H22O11 + 12 O2  12 CO2 + 11 H2O

1 C12H22O11 molecule: 12 O2 molecules : 12 CO2

molecules : 11 H2O molecules.

Applications of the mole ratio concept

grams <--> moles <--> moles <--> grams

if you take 2.0mL of a 7.0 ppm NaOH solution and dilute it to 250.0mL, calculate the final concentration in ppm.
Oduvanchick [21]

Answer:

C₂ = 0.056 ppm

Explanation:

Given data:

Initial volume = 2.0 mL

Initial concentration = 7.0 ppm

Final volume = 250.0 mL

Final concentration = ?

Solution:

Formula:

C₁V₁ = C₂V₂

C₁ = Initial concentration

V₁ = Initial volume

C₂ = Final concentration

V₂ = Final volume

Now we will put the values in formula.

C₁V₁ = C₂V₂

7.0 ppm × 2.0 mL = C₂ × 250.0 mL

C₂ = 14.0 ppm.mL /250.0 mL

C₂ = 0.056 ppm
