The RMM is used in many sorts of calculations in chemistry, and so you must be able to calculate it to answer all the other calculations you might meet. For a solution, mass percent equals the mass of an element in one mole of the compound divided by the molar mass of the compound, multiplied by 100%. A compound is analyzed and found to contain 12.1% carbon, 16.2% oxygen, and 71.7% chlorine (by mass). questions: C = 12, Cl = 35.5, Fe = 56, H = 1, Mg = 24, N = 14, Na = 23, O = 16, S = 32, By now I assume you can do formula mass calculations and read formula without any trouble, so ALL the detail of such calculations is NOT shown, just the bare essentials! D) The mass of one isotope must be lighter then 35.5 amu while the mass of the other isotope is heavier than 35.5 amu D Two naturally occuring isotopes exist for the hypothetical element Dippium. Median response time is 34 minutes and may be longer for new subjects. annette7 annette7 Answer: To find the molar mass of nitric acid HNO3. The two masses have the same numerical value, but the units are different: The molecular mass is the mass of 1 molecule while the molar mass is the mass of 6.022 × 10 23 molecules. are solved by group of students and teacher of Class 9, which is also the largest student star outlined.
