# How to calculate the number of moles in 6.6 grams of ascorbic acid vitamin C equals C6H8O6 equals 176 grams / moles?

Jan 28, 2018

$\text{6.6 g"/"176 g/mol" = "0.038 moles}$

#### Explanation:

The molar mass of ascorbic acid is $\text{176 grams/mole'}$. This means that every $1$ mole of ascorbic acid will have a mass of $176$ grams.

This can be mathematically expressed by the equation:

$\text{moles" xx "molar mass" = "mass}$

That is:

$\text{1 mole" xx "176 grams/mole" = "176 g}$

By transposing the above equation, we get:

$\text{mass"/"molar mass" = "moles}$

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