- match the correct definition with the right word.arrow_forwardI know you don't answer graded questions and I am not looking for you to straight up give me the answer to this but how do I even start? like I said before I know that the highest peak is 16amu which is Oxygen but do I just the vertical bar as a ratio? Like the next bar to the left (15amu?) is like 90% intensity? so like 9:10 ratio? There isn't even a 15amu element so please just give me some idea where to start. The place in the book it tells you to go to read has nothing about this stuff, its about finding empirical formulas from mass or percentages.... please help me!arrow_forwardWith the image attached please do the calculations/calculate what is highlighted in yellow please Please also calculate - percent % error in molar mass - percent % error in pKa Please please please answer as fast as possiblearrow_forward
