Formula for titration

Question 1

How do you calculate amount (in moles) to the number of particles?

Answer 1

Amount (in moles) multiply by 6.02 x 10 to the power of 23 to calculate the number of particles.

Question 2

How do you calculate the amount (in moles) by number of particles?

Answer 2

No. Of particles divide by 6.02 x 10 to the power of 23

Question 3

How do you calculate the mass of the substance based on the amount (in moles)?

Answer 3

Amount (in moles) multiply by molar mass will allow you to obtain the mass of the substance.

Question 4

How do you calculate the amount (in moles) based on the mass of the substance?

Answer 4

mass divide by molar mass allows to obtain the amount (in moles)

Question 5

How do you calculate the mass based on the number of particles?

Answer 5

number of particles divide by 6.02 x 10 to the power of 23 multiply by molar mass allows you to calculate the mass.

Question 6

How do you calculate the no. Of particles based on the mass of substance?

Answer 6

mass of substance divided by molar mass multiply by 6.02 x 10 to the power of 23.

Question 7

How do you perform calculations involving masses?

Answer 7

1. Calculate the molar mass of the substance where the mass of it is given.
2. Calculate the amount of the substance fermented
3. From the equation, balance it and derive the mole ratio
4. Hence, amount of the other substance produced
5. Molar mass of the other substance
6. Calculate the mass of the substance formed

Question 8

The molar it’s of a solution can be calculated using which equation?

Answer 8

Molarity of a solution (mol/dm cube) = no. Of moles of solute (in mol)/ volume of solution (in dm cube)

Question 9

What is the formula for mass concentration of a solution?

Answer 9

Mass concentration of a solution (g dm to the power of -3) = mole concentration of the solution (mol dm to the power of -3) x molar mass of solute (g mol to the power of -1)
