- You have conducted an experiment where you obtained 22.4g ZnCl2. The accepted value is 22.7g. What is the error and relative (%) error?arrow_forwardA compound containing only carbon, nitrogen, oxygen, and hydrogen contains four carbon atoms. If the M+ peak in its mass spectrum appears at m/z = 87, then how many nitrogen atoms does it contain?arrow_forwardBy knowing the natural abundance of minor isotopes, it's possible to calculate the relative heights of M+ and M+1 peaks. If natural abundances are 12C - 98.9% and 13C - 1.10%, what are the relative heights, to the nearest 0.1%, of the M+ and M+1 peaks in the mass spectrum of benzene, C6H6? Ignore the contributions of isotopes like 2H (deuterium; 0.015% natural abundance) and 17O (0.04% natural abundance) that are small.The relative heights are, in order of increasing mass: 100 to ____arrow_forward
- There is mass spectrum. What is the molecule compound name?arrow_forwardWhat type of compounds/molecules can be detected using LC-MS and what mass range or molecular mass ranges can be detected using LC-MS?arrow_forwardWhat is responsible for the small peak at m/z = 17 in the mass spectrum of CH4?arrow_forward
- If the mass spectrum of a sample has a 7.7% M+1 peak compared to a 100% M+ peak, how many carbon atoms are we then likely to have in our chemical formula?arrow_forwardFrom graphical analysis of a calibration plot, you generated the line y=2543.23x + 0.0034. Your sample had an Absorbance of 0.142. What is the concentration?arrow_forwardhow would i go about answering thisarrow_forward
