I need help understanding how to do this, can you please show me how you get the CFU/mL

I need help with one of my pre-lab questions which I want to understand. Its question number 2, the one that highlighted. I don't want to make it over-complicated, I want something that I can understand.

Based on the data given answer the questions. Please ??

help please answer in text form with proper workings and explanation for each and every part and steps with concept and introduction no AI no copy paste remember answer must be in proper format with all working

You will write an informal procedure in your lab notebook, and after lab, write a written procedure for the Post-lab. Match the following with the type of procedure. Hint: Refer to the 'Guide for Success in the General Chemistry Laboratory' in the front matter of your lab manual for further information regarding the differences between these two types of procedures. Contains as much detail as possible (i.e. type of glassware, concentrations) Contains only enough detail to concisely convey to the reader what occurred. Written step-by-step Written in paragraph form Written in past passive voice ✓ [Choose ] Informal procedure Written procedure [Choose] [Choose] [Choose ] [Choose ]

Instructions You are required to produce a short lab report using the information given in the accompanying document, ‘Lab report assessment_student data’. This document introduces an experiment, and also provides a set of experimental data for this experiment. You are required to use this data to perform steps 8 and 9 of the procedure. This includes calculations of a particular value, and then comparison to the true value. Consider any experimental errors when comparing calculated values and true values. Your report should be between 300 and 500 words (including all table contents and titles of tables and graphs). Your lab report should consist of three sections only: • Experimental • Results and Discussion • Conclusion You do NOT need to include an introduction section. Your experimental section should be written in appropriate lab report format, (passive voice, 3 rd person, in paragraphs). Your results and discussion section should contain the data presented in table format, and…

Hi, I am having trouble understanding how to do dilution factors for these tubes can you show me how to get the DF please?

Now that you know the moles of NaOH used for each trial as well as the volume of NaOH used for each trial, calculate the concentration of the NaOH that you made in lab for each trial.  Round to the ten-thousandths place please.

All changes save 7. When two solutions are mixed, a color change occurs. The data tables show the time between mixing and the color change for two sets of conditions. For Condition One, the solution concentrations were constant and temperature varied. For Condition Two, the temperature was constant and concentrations varied. Condition One: Concentration Time for Temperature (°C) Sample Color to Change 1 10° 36 sec 22° 14 sec Condition Two: Temperature Time for Concentration Sample Color to % Change 1. 100% 15 sec 2. 50% 24 sec Which of these statements is true according to the data? O The reaction rate is greater at 22°C than at 10°C. O Reducing the temperature increases the rate of the reaction. The reaction is affected by changes in temperature not by changes in concentration. O Decreasing the concentration increases the reaction rate. PREVIOUS 17 of 25 NEXT SAVE & EXIT
