INTRODUCTORY CHEMISTRY W/ACCESS
- If 1.00mol/l of nax contains 4.2% solute by mass, what is the atomic mass of x?arrow_forwardTo three significant digits, what is the mass percentage of iron in the compound Fe2O3?arrow_forwardAn 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_forward
- What is the molar mass of zinc sulfate heptahydrate, ZnSO4·7H2O?arrow_forward3.98 The characteristic odor of decaying flesh is due to the presence of various nitrogen-containing compounds. One such compound, called putrescine, was analyzed and found to contain 54.49% carbon, 13.72% hydrogen, and 31.78% nitrogen by mass. If the molar mass of putrescine is known to be between 85 and 105, what is its molecular formula?arrow_forwardA sample of a hydrocarbon (a compound consisting of only carbon and hydrogen) contains 2.59 1023 atoms of hydrogen and is 17.3% hydrogen by mass. If the molar mass of the hydrocarbon is between 55 and 65 g/mol, what amount (moles) of compound is present, and what is the mass of the sample?arrow_forward
