A sample of propane(c3h8)has 3.84x10^24 H atoms. a) how many carbon atoms does the sample contain?
b) what is the total mass of the sample?

Avariable that is not being directly tested during an experiment should be

Chromosome 17 is made of over million base pairs.

Amixture initially contains a, b, and c in the following concentrations: [a] = 0.300 m , [b] = 1.05 m , and [c] = 0.550 m . the following reaction occurs and equilibrium is established: a+2b⇌c at equilibrium, [a] = 0.140 m and [c] = 0.710 m . calculate the value of the equilibrium constant, kc.
