How much is a mole of rice?

Doing that for a year we need 9.89 x 10 ^ 16 little, individual grains of rice. Knowing that a mole is 6.022 x 10 ^ 23, we can devide with 9.89 x 10 ^ 16, and – this might make you shiver with excitement – we get that a mole of rice grains will feed the current population of our planet for … 6088978 years!!

How do you find moles of rice?

Students will need to find the mass and volume of single rice grain, by massing and taking the volume of 50-10 grains and then dividing by the number of grains. Once they know the volume of one grain, they can find the volume of a mole of grains.

How much is a mole of sand?

Now imagine a mole of sand particles. That would be 6.02 x 1023 grains of sand. How big would it be? If you put all of that sand in a cube shaped box, it would be about 4,400 meters tall, 4,400 meters wide and 4,400 meters deep.
