1 mole is 6.022*1023 atoms, avagradro's number. 1 mole of pennies is equal to 6.022*1023 pennies.
3.5*10-16 mol pennies * 6.022*1023 pennies/1 mol pennies = 210,770,000 pennies
If you had 3.5*10-16 moles of pennies, you would have 2.1077*108 pennies.

2.8 moles of gold would be 550g of gold. Multiplying the amount of moles by the molar mass (197.0 grams/moles) will give you the grams by cancelling out the moles units.
1.5 moles of Hydrogen. In every mole of H2SO4 (Sulfuric Acid) there are 2 moles of Hydrogen atoms. So, in .75 moles of Sulfuric Acid, there would be 1.5 (double the moles of sulfuric acid) moles of Hydrogen.

The Sun has a diameter of 865,000 miles, and if a penny is 5/8 inch across that means that 275 billion pennies would go round it once. The moles bit needs clarification.
It would depend on how many pennies they had!
1016 millimetres = 40 inches

As there are 100 pennies in a dollar, 500 dollars would yield 50,000 pennies.
Approx. 0,5 moles.

The answer is 1.35 moles.425 g of UF4 would be 1.35 moles.
12 moles Li
16 ounces (or 1 pound) of pennies would be a total of about 181 pennies.
Since there are 100 pennies to the dollar, there would be 1,000,000 (one million) pennies in $10,000.00
