About 1.2 times ten to the 24th power. This is so much more money than has ever existed that it's almost meaningless. (To give some perspective, there's about 1.2 times ten to the 12th dollars in circulation right now; if you piled all of it up, it would take a trillion such piles to make two moles of dollars.)
There are 200 pennies in 2 dollars.
There are 8 zeroes in the number for 2 million dollars
5 dollars, 2 cents.
5 zeros for the dollars, 2 for the cents
One 10 dollar, 2 five dollars, 5 two dollars, and 10 one dollars.
2 moles, if you can find the proper catalyst, or set of reactions to complete the reaction.
there are two moles produced in potassium nitrate.
5 moles RbNO3 (3 moles O2/2 moles RbNO3) = 7.5 moles oxygen gas produced
1 mole of water is 18g. 36g of water is thereforeequivalent to 2 moles. 2 moles of water contains 4 moles of hydrogen and 2 moles of oxygen and so there are6 moles of atoms in 2 moles of water. 6 moles of atoms x (3.6x10^24) = 36.1x10^24 atoms
2.,7 moles of glucose have 486,432 g.
2N + 3H2 -> 2NH3 18 moles H2 (2 moles NH3/3 moles H2) = 12 mole ammonia
1,5665 moles barium phosphate
2KClO3 --> 2KCl + 3O2For every 3 moles of oxygen gas produced, 2 moles of potassium chlorate are used.6 moles O2 * (2 moles KClO3 reacted / 3 moles O2 produced) = 4 moles KClO3
N2 + 3H2 -----> 2NH3 so 3 moles of hydrogen produce 2 moles of ammonia. Therefore 12.0 moles of hydrogen will produce 8 moles of ammonia.

Calcium Nitrtae is Ca(NO3)2 and so there are two moles of nitrate per mole of calcium nitrate. Thus there are 2 x 2.50 = 5.0 moles of nitrate present.
