Chapter 5 Formulas

Question 1

What is the % by Volume Formula?

Answer 1

C = Vsolute / Vsolution x 100%

Question 2

What is the % weight by Volume Formula?

Answer 2

C = msolute / Vsolution x 100%

Question 3

What is the % weight by weight Formula?

Answer 3

C = msolute / msolution x 100%

Question 4

What is the general formula for Parts Per Million?

Answer 4

ppm = msolute (g) / msolvent (g) x 10 to the power of 6

Question 5

When ppm can be expressed as 1 milligram per kilogram what is the formula?

Answer 5

ppm = msolute (mg) / msolvent (kg)

Question 6

When ppm can be expressed as 1 milligram per liter what is the formula?

Answer 6

ppm = msolute (mg) / Vsolvent (L)

Question 7

What is the formula for Concentration?

Answer 7

Concentration = number of moles of solute / number of liters of solution

Question 8

To find concentration what is the formula?

Answer 8

C = nsolute / Vsolution

Question 9

To find Volume what is the formula?

Answer 9

Vsolution = nsolute / [ ]

Question 10

To find nsolute what is the formula?

Answer 10

nsolute = [ ] x Vsolution

Question 11

To find mass

Answer 11

Mnew/Vnew = Msolute/Vsolution

Question 12

What is the formula for dilution?

Answer 12

C1V1 = C2V2

Question 13

To find mass what is the formula?

Answer 13

mass = number of moles x Molar Mass

Question 14

To find number of moles what is the formula?

Answer 14

number of moles = mass / Molar Mass

Question 15

To find Molar Mass what is the formula?

Answer 15

Molar Mass = number of moles / mass
