Homework. Chu x : C Grades loe Nickel â www.webassagn.net/webStudent/Assignment.Responses/tutorial?dep: 18344958 Step 1 of 5 Calculate the molar mass of the given substance. (Enter an unrounded value.) The given substance is ethanol, C2HsOH. The formula mass of C2HsOH is the following. C2H5OH = (2)(average atomic mass of C) + (6)(average atomic mass of H) + (1)(average atomic mass of O) (2)(12.01 amu)+ (6)(1.008 amu) + (1)(16.00 amu) amu Formula mass in amu equals molar mass in g/mol, so the molar mass of C2HsOH-S g/mol. Determine the number of significant figures for a calculation Given the equation relating the molar mass of a substance to its formula mass, calculate Calculate the molecular mass or formula mass of a substance the molar mass of a substance Supporting Materials Periodic Table Constants and Factors Supplemental Data Additional Materials Section 4 4
