Molar Mass Date:

Molar Mass The sum of the atomic mass of each atom in the chemical formula. Tells you the mass of one mole of a compound. Unit: g/mol – MUST add name of compound Whats a mole? Lets listen!

A mole is an animal that burrows in the ground, or a spot on your chin that youve gotta shave around. But theres another kind of mole of interest to me and thats the kind of mole they use in chemistry!

A mole is a unit or have you heard, containing six times ten to the twenty-third. Thats a six with twenty three zeros at the end, a much too big a number to comprehend!

Say you had a mole of pennies to distribute round the world, Give to each of the five billion grownups, boys and girls There wouldnt be a single soul down and out of luck, Cause everybody in the world would get a trillion bucks.

Or say you had a mole of paper and stacked it toward the sky Papers awful thin, but that pile would get so high, Itd reach up into outer space, in fact I think youd find Itd go up to the moon and back, eighty billion times.

Suppose a mole of marshmallows fell upon the planet, over each square inch of land and sea, think that you could stand it? That layer would be twelve miles high and of course block out the sun, Were talking close to five million trillion tons!

Well, maybe we could save ourselves if we all started eatin. One marshmallow each second, not two cause thatd be cheatin. With five billion people munching, how long do you think itd take? Forty million years – and thats without a bathroom break!

A mole is a unit or have you heard, containing six times ten to the twenty-third. Thats a six with twenty three zeros at the end, a much too big a number to comprehend!

But say you had a mole of atoms, would the pile be immense? Should I say the answer now or leave you in suspense? Well, atoms are so very, very small you understand, you could hold a mole of atoms in the palm of your hand. So shake a little sugar in the middle of your palm, now you dont want to spill it, so try and stay calm. You hardly can imagine and barely realize, theres more atoms in that sugar than stars up in the sky!
