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 8 zeroes in the number for 2 million dollars
5 dollars, 2 cents.
Funny pennies make two dollars
5 zeros for the dollars, 2 for the cents
One 10 dollar, 2 five dollars, 5 two dollars, and 10 one dollars.
2 moles of Ca and 4 moles of OH
This reaction is:2 Al + 2 H2O + 2 NaOH = 2 NaAlO2 + 3 H2From 4 moles of Al 6 moles of hydrogen are obtained.
2 moles, if you can find the proper catalyst, or set of reactions to complete the reaction.
It takes 2 moles of NO to form 2 moles of NO2, so to form 4.67 moles of NO2 you would need 4.67 moles of NO.
The answer is 3 moles of Cu)NO3)2..
There are 2 moles of potassium cations (K+) in 1 mole of K2SO4, so in 1.30 moles of K2SO4 there would be 2.60 moles of potassium cations.
The answer is 2 moles.
12 moles
5 moles RbNO3 (3 moles O2/2 moles RbNO3) = 7.5 moles oxygen gas produced
4 moles also 2 moles of oxygen will be consumed
There are 18 moles of hydrogen atoms in 2 moles of C8H18 because each mole of C8H18 contains 18 hydrogen atoms.
The answer is 10 moles of carbon monoxide.2 C + O2 = 2 CO
