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

A cooking recipe lists adding 3.0 qt of water as a step. How many mL of water is this?

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.
