- Suppose that the atomic mass of C-12 is taken to be 5.000 amu and that a mole is defined as the number of atoms in 5.000 kg of carbon-12. How many atoms would there be in one mole under these conditions? (Hint: There are 6.0221023 C atoms in 12.00 g of C-12.)arrow_forwardA substance has the molecular formula C6H12O2. What is its empirical formula?arrow_forwardThe molar mass of caffeine is 194.19 g. Is the molecularformula of caffeine C4H5N2O or C8H10N4O2?arrow_forward
- An industrial detergent was found to be composed of 57.72% C, 8.073% H, 17.09% O, by mass and the remaining was an unspecified element, X. It was also found that the moles of X was twice that of the moles of O. Given that the molar mass is 566.92 g/mol and that the molar mass is twice the molar mass of that of the emperical formula, what is the molecular formula in terms of X? Identify what element X is by explicit calculation.arrow_forwardWhat is the mass, in grams of 9.47*10^24 molecules of methanol?arrow_forwardThe empirical formula for C6H13 is-arrow_forward
- How many H atoms are in 75.7 g of acetaldehyde, C2H4O?arrow_forwardThe following diagram represents the collection of CO2 andH2O molecules formed by complete combustion of a hydrocarbon.What is the empirical formula of the hydrocarbon?arrow_forwardWhat is the percent mass of iron in the compound Fe3O4arrow_forward
- What three conversation factors and in what order would you use them to convert the mass of a compound into atoms of a particular element in that compound- for example from 1.00 g aspirin (C9H8O4) to number of hydrogen atoms in the 1.00 g sample?arrow_forwardHow many moles of chlorine atoms are there in a sample that consists of 1.89e+22 molecules of iodine trichloride?arrow_forwardCaffeine has the formula C8H10N4O2 . If an average cup of coffee contains approximately 125 mg of caffeine, how many moles of caffeine are in one cup?arrow_forward
