10.How many formula units are in 0.456 grams of Ca3(PO4)2? Science. The answer is 0.508gram The molecular mass for aspirin (C9H8O4) should be 180g/mol. A common request on this site is to convert grams to moles. What is Molar Mass? - Definition, Formula & Examples How do you find molar mass from moles and mass? But we can also say that the "molar mass" of carbon is 12.01 g/mole. So, Molar mass of Aspirin (C9H8O4) = Molar mass of 9 Carbon (C) atoms + Molar mass of 8 Hydrogen (H) atoms + Molar mass of 4 Oxygen (O) atoms.= (12.011) 9 + (1.008) 8 + (15.999) 4= 108.099 + 8.064 + 63.996= 180.159 g/mol. You can also look up the molar mass. The average mass of an aspirin molecule is 180. Following are the steps: Determine how many atoms of each different element are in the formula. 1.09 x 1021 1 grams C9H8O4 is equal to 0.0055507011590197 . Computing molecular weight molecular mass To calculate molecular weight of a chemical compound enter it's formula, specify its isotope mass number after each element in square brackets. For example, the atomic mass of carbon, C, is 12.01 amu. The mass in grams of the aspirin is 0.194 g. From the question, We are to determine the mass in grams of 6.510 molecules of aspirin (CHO). (b) What is the mass, in grams, of 0.0573 mol of iron(III) Robert S. You can view more details on each measurement unit: molecular weight of C9H8O4 or mol This compound is also known as Aspirin. Atomic Mass: 12.0107 Chemistry Chapter 7!!! Flashcards | Quizlet Base the number of significant digits on the number given in the problem for the number of molecules. the mass in grams of a mole of any pure substance atomic mass the mass in amus of an atom of an element Avogadro's number the number of representative particles in a mole of a substance mole (mol) 6.02 x 10^23 representative particles of a substance empirical formula the formula that gives the lowest whole-number ratio of the elements in a compound If you're getting the incorrect answer for this type of problem, the usual cause is having the number of atoms wrong. This is not the same as molecular mass, which is the mass of a single molecule of well-defined isotopes. list three common ways that matter is measured, Which contains more molecules:1.00mol H2O2, 1.00 mol C2H6, or 1.00 mol CO, Which containsmore molecules: 1.00mol H2O2, 1.00 mol C2H6, or 1.00 mol CO, Find the number of representative particles in each substance: 3.00 mol Sn, Find the number of representative particles in each substance: 0.400 mol KCL, Find the number of representative particles in each substance: 7.50 mol SO2, Find the number of representative particles in each substance: 4.80 * 10^-3 mol NaI, Calculate the molar mass of each substance: H3PO4, Calculate the molar mass of each substance: N2O3, Calculate the molar mass of each substance: CaCO3, Calculate the molar mass of each substance: (NH4)2SO4, Calculate the molar mass of each substance: C4H9O2, Calculate the molar mass of each substance: Br2, Calculate the mass of 1.00 mol of each substance: silicon dioxide (SiO2), Calculate the mass of 1.00 mol of each substance: diatomic nitrogen (N2), Calculate the mass of 1.00 mol of each substance: iron(III) hydroxide (Fe(OH)3), Calculate the mass of 1.00 mol of each substance: copper (Cu), List the steps you would take to calculate the molar mass of any compound, to find the molar mass take out a periodic table and look up the atomic mass[number below each element in the table that i gave the link to] of S [sulfer] which you will find is 32 [round to the nearest whole number] then find the atomic mass of O [oxygen] which you will find is 16.
