Okay, So the molecule of formula for glassine is, and next to see it's to see a witch. Let me present it. It is. And Mitch two. See? It's too. See you, bro. Glassine is the simplest amino acid. The molecule off glassine has an amino group on a car Boxley group, which is attached to a metal in group or option B. The Mullah Omar's off Tyson is calculated by adding the atomic mass off all its considering. All off hm molecule marks off the considerate are represented as follows, while the molar mass is some off it, adding all off them give this molar mass equals 75 points. 07 or option C B No mass off one mole off laziness 75.3 Bye for the mass off. Three more off Bly scene is three into 75.7 which gives US 225.21 auction d the Mullah Omar's off blessing again. 75.7 while the atomic mass off nitrogenous 14. So for calculating the percentage of my Trojan, we need to divide atomic mass off night origin from the total molecule mus multiplied with 100 which gives US nitrogen percent ages 18.6
