Mole to Gram Conversion Concepts

The video tutorial explains how to convert moles of water to grams. It begins by identifying the given and target units, then sets up the problem using a conversion factor. The gram formula mass (GFM) of water is calculated using the periodic table. The conversion is performed by multiplying the given moles by the GFM, and the result is verified for reasonableness by comparing it to an estimated value.

What is the first step in solving a conversion problem from moles to grams?

• Calculate the gram formula mass.

• Perform the multiplication.

• Identify the given and required information.

• Set up the conversion factor.

What is the purpose of using a conversion factor in this problem?

• To cancel out the units of moles.

• To determine the molecular weight.

• To find the number of moles.

• To cancel out the units of grams.

How do you find the gram formula mass (GFM) of water?

• By subtracting the atomic mass of oxygen from hydrogen.

• By dividing the atomic mass of hydrogen by two.

• By multiplying the atomic mass of oxygen by two.

• By adding the atomic masses of hydrogen and oxygen.
