How do you convert 1.55 moles of water to grams?

Answer 1

By using the molar mass of water.

The molar mass, or the weight in grams of one mole (g/mol), is needed to convert moles to grams.

Each element has its own specific molar mass. For water (#H_2O#) take the sum of the molar masses of #2# hydrogen and #1# oxygen atom:

This means that #1# mole of water weighs #18.015# gram. But you have #1.55# moles of water, so you multiply:

The molar mass of water (H2O), which is roughly 18.015 grams per mole, can be used to convert moles to grams: 1.55 moles of water x 18.015 grams/mole = 27.89 grams of water

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
