Converting Grams to Atoms

This video tutorial explains how to convert grams of silver to atoms. It begins by introducing the concept of conversion and the need to use molar mass and Avogadro's number. The process involves dividing the given grams of silver by its molar mass to find moles, then multiplying the moles by Avogadro's number to find the number of atoms. The tutorial uses a specific example with 112.5 grams of silver, resulting in 6.26 x 10^23 atoms. The video concludes with a recap of the steps involved in the conversion process.

What is the primary goal of the video tutorial?

• To convert grams of silver to atoms

• To measure the density of silver

• To determine the melting point of silver

• To calculate the volume of silver

Why can't we directly convert grams to atoms?

• Because grams are not a unit of mass

• Because we need to convert to moles first

• Because atoms are too small to measure

• Because atoms do not exist in grams

What is the molar mass of silver used in the calculation?

• 6.02 g/mol

• 112.50 g/mol

• 107.87 g/mol

• 100.00 g/mol

How many moles of silver are there in 112.5 grams?

• 1.04 moles

• 2.00 moles

• 0.50 moles

• 1.50 moles

What constant is used to convert moles to atoms?

• Planck's constant

• Gravitational constant

• Boltzmann's constant

• Avogadro's number

What is Avogadro's number?

• 3.14 x 10^23

• 1.61 x 10^23

• 6.02 x 10^23

• 9.81 x 10^23

How many atoms of silver are in 112.5 grams?

• 6.26 x 10^23 atoms

• 1.04 x 10^23 atoms

• 5.00 x 10^23 atoms

• 7.00 x 10^23 atoms

What is the first step in converting grams to atoms?

• Multiply by Avogadro's number

• Divide by the molar mass

• Add the atomic number

• Subtract the atomic mass

What is the final step in the conversion process?

• Divide by the atomic number

• Subtract the atomic mass

• Multiply by Avogadro's number

• Add the molar mass
