Web18 jul. 2005 · Before we can calculate the mass of the compound we must determine the charge state of the two peaks. Step 1 Understand that the peak value observed in the spectrum equals mass divided by charge and that the mass is the mass of the molecule plus any adducts (protons) 190.1 = mass/charge and ... m+1=190.1(z+1) and m = 379.2(z) and : WebThe molecular ion peaks (M + and M+2) each contain one chlorine atom – but the chlorine can be either of the two chlorine isotopes, 35 Cl and 37 Cl. The molecular ion containing the 35 Cl isotope has a relative formula mass of 78. The one containing 37 Cl has a relative formula mass of 80 – hence the two lines at m/z = 78 and m/z = 80. merm wicked tuna
