# I have some "Mole" questions?

How many moles are in 84g ?

and in 5g?

Relevance

"84g citric acid and 5g sugar"

The formula for citric acid is H3C6H5O7 and its molar mass is 192.123 g/mol. To get the moles, we divide:

84 g / 192.123 g/mol = 0.43722 mol (round off more as you see fit)

==========

There are many compounds under the generic name of sugar. Let's use glucose, C6H12O6.

5 g / 180.1548 g/mol = 0.027754 mol (round off more as you see fit)

• It depends on the mole really, a star nosed mole weighs far less than a european mole.

• Moles (mol) is a quantity of things like atoms

Mass (kg) is weight. They are related by "Molar Mass" • Log in to reply to the answers

• Depends on the substance

Each substance has a molar mass

Example:

hydrogen  1.0008g/mol

Oxygen 15.999g/mol

1 Mole of Sodium bicarbonate NaHCO₃ is 84.007g/mol

So...

What substance?

• Oh yeah ofc. 84g citric acid and 5g sugar

• Mole is not a unit of mass. Each element (and therefore compound) has its own molar mass so you would need to know what substance you are referring to. For example, 84g of hydrogen gas is 42 moles. 84g of of sugar is 0.25 moles.

• yes your right. 84g citric acid and 5g sugar is what i meant
