John and Alex were asked to make a 0.70 M solution. John measure out .35 L from the 2.0 M solution before asking how much soluti
nasty-shy [4]

Answer:

1.0 L

Explanation:

Given data

  • Initial volume (V₁): 0.35 L
  • Initial concentration (C₁): 2.0 M
  • Final volume (V₂): ?
  • Final concentration (C₂): 0.70 M

John and Alex prepared a diluted solution from a concentrated one. We can find the volume of the diluted solution using the dilution rule.

C₁ × V₁ = C₂ × V₂

V₂ = C₁ × V₁ / C₂

V₂ = 2.0 M × 0.35 L / 0.70 M

V₂ = 1.0 L

Select the correct empirical formula for each molecular formula given.
Sauron [17]

Answer:

CH₂O

Explanation:

Empirical formula:

It is the simplest formula gives the ratio of atoms of different elements in small whole number.

Molecular formula:

Molecular formula shows the actual whole number ratio of elements present in compound.

Given molecular formula: C₆H₁₂O₆

Empirical formula = CH₂O

In molecular formula six moles of carbon six moles of oxygen and 12 moles of hydrogen are present.

To get the smallest whole number we divide the each number by 6 and we get CH₂O which is empirical formula of C₆H₁₂O₆.
