To calculate the number of moles from grams, you must divide by the substance's molar mass
The answer is 0,2686 moles.
15 grams of nitrogen are equal to 1,071 moles.
15 moles of 02 equal 480 g.
15 moles O2 (32 grams/1 mole O2) = 480 grams
CO2's molar mass is 44g/mol, so 15/44=0.34mol CO2.
You have2KClO3 ==> 2KCl + 3O2 as the balanced equation 25 g KClO3 x 1 mole/123 g = 0.20 moles moles KCl formed = 0.20 moles KClO3 x 2 moles KCl/2 moles KClO3 = 0.20 moles KCl formed grams KCl = 0.20 moles x 74.5 g/mole = 14.9 g = 15 grams of KCl formed
15g Li * (1mol Li / 6.941g Li) = 2.16 mol Li
15 grams of butter is equivalent to 15 grams.
From the periodic table, lithium has an atomic weight of 6.941. The molar mass of an element is the atomic weight in grams. Therefore, 1 mole Li = 6.941g Li Therefore, moles Li = 15g Li X 1 mole Li/6.941g Li = 2.2 moles Li
The equivalent is 1,6.10e-15 moles.

The Answer is.56 moles OR 0.56 moles
15 kilograms = 15,000 grams
15 ounces = 425.2 grams
15 grains = about 0.971 grams.
15 grams = 0.53 ounces.
15 grams is 0.033 pound.
15 ounces is 425.24 grams.
5 Cr2O3 = 15 H2 = 10 Cr + 15 H2O so 15 moles of hydrogen gas
