Calculating Mass of Silver Atoms

The video tutorial explains how to find the mass of one atom of silver by using its average atomic mass and dividing it by Avogadro's number. It also covers converting this mass into kilograms and how to calculate the mass of a specific isotope, silver 109, using its mass number.

What is the first step in finding the mass of one atom of silver?

• Subtract Avogadro's number from the atomic mass.

• Multiply the atomic mass by Avogadro's number.

• Divide the molar mass by Avogadro's number.

• Add the atomic mass to Avogadro's number.

What units are used for the average atomic mass of silver?

• Grams per mole

• Atoms per mole

• Moles per gram

• Kilograms per mole

How do you calculate the mass of a silver atom?

• Add the atomic mass to the number of atoms.

• Multiply the atomic mass by the number of atoms.

• Divide the atomic mass by Avogadro's number.

• Subtract the number of atoms from the atomic mass.

What is the result of dividing the average atomic mass of silver by Avogadro's number?

• The number of moles in a gram of silver.

• The mass of one mole of silver atoms.

• The mass of one atom of silver.

• The number of atoms in a mole of silver.

How can the mass of a silver atom be expressed in kilograms?

• Multiply the mass in grams by 1000.

• Divide the mass in grams by 1000.

• Add 1000 to the mass in grams.

• Subtract 1000 from the mass in grams.

What is the mass of one atom of silver in kilograms?

• 1.79 * 10^-23 kg

• 1.79 * 10^-25 kg

• 1.79 * 10^-29 kg

• 1.79 * 10^-27 kg

How do you find the mass of a silver-109 isotope?

• Subtract the mass number of silver-109 from Avogadro's number.
