Can you help me answer this questions 4 and 5, this is from the previous question I just split my question, thanks

Using the data below (included for context), what is the equation for the trendline for the data points that fall in the linear range  (linear range was found to be timepoints 1 min to 4 min,)? Your answer should be in the form of y = mx + b. Make sure that your trendline only includes the data points that fall in the linear range. In order to determine the trendline using Excel, you may need to create a new graph that only includes the earlier data points. With your new trendline, what is the initial velocity when 1 nM OXA-M290 is mixed with 60 μM nitrocefin? Make sure to include units in your answer. Context: DO NOT ANSWER Concentration of hydrolyzed nitrocefin at 20 time points. Graph attached below Time (min)  Concentration (μM)  0.5  6.01  1  11.78  1.5  17.6  2  23.51  2.5  29.58  3  35.31  3.5  39.73  4  44.5  4.5  48.18  5  50.05  5.5  52.72  6  54.01  6.5  55.06  7  55.65  7.5…

1. A farmer needs to administer a dose of albendazole dewormer to a cow that weighs 992 lbs. The dosage recommended by his veterinarian is 10 mg per kg of body weight. How many mg of albendazole should the farmer administer? [1 kg = 2.205 lbs] Calculate the weight of this cow in kg. Round to 4 decimal places. Then, using the exact weight in kg (not your rounded weight) and the medical conversion, determine the dose that the cow should get in mg. Round to two decimal places.Using your answer from the previous slide, if albendazole is only available as a liquid, and each milliliter of the liquid contains 125 mg of albendazole, how many mL of the liquid should the farmer administer?  Round to two decimal places.   2.The doctor orders a single dose of 20 mg/kg for every does dose of amoxicillin oral suspension for a toddler who weighs 25 lbs. [1 kg = 2.205 lbs] Helpful hint: Always start with weight first! Calculate the weight of this toddler in kg. Round to 4 decimal places. Then,…

5. The Handbook of Chemistry and Physics lists the density of a certain liguid to be 07988 g/mL. Fred experimentally finds this liquid to have a density of 0.7914 a/ml The teacher allows up to +/- 0.500% error to make an "A" on the lab. Did Fred make an "A"? Prove your answer,

Not sure what I am doing wrong here...

2. A student is told to determine the density of a solid unknown cylinder. The mass of the unknown cylinder is 56.38 grams. The unknown cylinder is 4.95 cm high and has a radius of 1.28 cm. The student measures the correct mass but measures the height as 4.96 cm and the radius as 1.30 cm. What will be the percent error in the student's density value? True- Experimental| x100 Percent Error = True

Please help me! Why is is it wrong and what is the correct answer?

Three samples of wood with the same volume were weighed. Sample A has a mass of 224.96 g, sample B has a mass of 0.55632 Ibs, and sample C has a mass of 0.30648 kg. Which block of wood has the highest density? Show your work. 2.21 Ibs = 1 kgNote: I have no idea how to solve this. Someone help me please!!!!

Advertised mass of Fe2+ per tablet is 18mg Trail 1 = 0.0200 g and Trail 2 = 0.00794 g Calculate the percent error from the advertised value for both trial 1 and trail 2. Provide one source of error (not human error) to account for your percent error, and explain how this source of error led to a higher or lower value (depending on your results) for the mass of iron in the vitamin tablet.
