Match each statement with the best answer.

What is the conversion factor used to convert between moles and particles?

In order to convert from grams to moles, you will ______________ by the conversion factor.

In order to convert from Liters of gas to moles, you will ______________ by the conversion factor.

In order to convert from moles to mass in grams, you will ___________ by the conversion factor.

What is the conversion factor used to convert between moles and mass in grams?

What is the conversion factor used to convert between moles and Liters of a gas?

Answer Choices:

multiply, 6.02 x 10^23 particles, divide, 22.4 L, Formula Mass

Solutions

Expert Solution

Conversion factor between moles and particles is 6.023 * 1023 particles

In order to convert mass to moles, you will divide by the conversion factor

in order to convert liter of gas to moles divide by conversion factor

In order to convert moles to mass in grams you will mulitiply by the conversion factor

conversion factor used to convert moles to mass in g is molecular mass

conversion factor used to convert moles to liters of gas is 22.4 L

At STP 1 mole of gas will occupy 22.4 L of volume so if divide the total volume of gas we will get the no. of moles of gas

Mass (g) = No. of moles ( moles) * Molar mass ( g/mol)
