#"6.6 g"/"176 g/mol" = "0.038 moles"#

Explanation:

The molar mass of ascorbic acid is #"176 grams/mole'"#. This means that every #1# mole of ascorbic acid will have a mass of #176# grams.

This can be mathematically expressed by the equation:

#"moles" xx "molar mass" = "mass"#

That is:

#"1 mole" xx "176 grams/mole" = "176 g"#

By transposing the above equation, we get:

#"mass"/"molar mass" = "moles"#

The mass is #"6.6 g"# and the molar mass is #"176 grams/mole"#.
Input those values into the equation and you will get the answer. The concept could be followed for any question of that sort.

NB the #"/"# symbol means to divide
