How many molecules are contained in 20.15 g of H2SO4 (Given atomic masses: H = 1.01, S = 32.06, 0 = 16.00). Use the proper number of significant figures.
A.)2.473 x 1023
B.)20.15
C.)1.213 x 1025
D.)1.237 x 1023

Ase your answer to this question on the information below. hydrocarbons and fissionable nuclei are among the sources used for the production of energy in the united states. a chemical reaction produces much less energy than a nuclear reaction per mole of reactant. the balanced chemical equation below represents the reaction of one molecule of a hydrocarbon with two molecules of oxygen. chemical equation: ch4 + 2o2 → co2 + 2h2o + 1.48 × 10−18 jthe nuclear equation below represents one of the many possible reactions for one fissionable nucleus. in this equation, x represents a missing product. nuclear equation: write an isotopic notation for the missing product represented by x in the nuclear equation.
