How many moles are in a pill containing 37.0mg of c12h22feo14

From the periodic table:
mass of carbon = 12 grams
mass of hydrogen = 1 gram
mass of iron = 55.84 grams
mass of oxygen = 16 grams
Therefore:
molar mass of C12H22FeO14 = 12(12) + 22(1) + 55.84 + 14(16) = 445.84 grams

number of moles = mass / molar mass
number of moles = 0.037 / 445.84 = 82.989 x 10^-6 moles

8.29 x 10^-5 moles. First lookup the atomic weights of all involved elements. Atomic weight carbon = 12.0107 Atomic weight hydrogen = 1.00794 Atomic weight iron = 55.845 Atomic weight oxygen = 15.999 Now calculate the molar mass 12 * 12.0107 + 22 * 1.00794 + 55.845 + 14 * 15.999 = 446.13408 g/mol Finally divide the mass by the molar mass to get the number of moles. Remember to convert the mass to grams. .0370 g / 446.13408 g/mol = 0.0000829347 moles Since 0.0000829347 is a rather inconvenient number to deal with, convert to scientific notation and round to 3 significant figures since that's the precision of the data we have. So the answer is: 8.29 x 10^-5 moles.

The independent variable is the type of music.the dependent variable is the pulse rate.the intervening variable is the age of the subject.if the mother does not like rock, her pulse is likely to not increase.the same might be true for the sister.the friend may like rap and gets excited.to establish cause/effect relationship, all of the subjects must be consistent.hope i .
