3. The FDA has determined that the acceptable daily intake (ADI) of FD&C Red 40 is 7.0 mg/kg body weight per day. In the USA, an 8 fl oz cup is a common measurement for liquids. a. Using the average concentration, calculate the grams of FD&C Red 40 in an 8 fl oz cup of your Kool-Aid flavor. There are 29.574 mL per 1 fl oz. b. If an average adult weighs 140 lbs (63.5 kg), how many 8 fl oz cups of your Kool- Aid flavor could one consume in a day before exceeding the ADI for FD&C Red 40? c. If an average child weighs 40 lbs (18.1 kg), how many 8 fl cups of your Kool-Aid flavor could one consume in a day before exceeding the ADI for FD&C Red 40? d. Based on the number of cups required to exceed the ADI for FD&C Red 40, do you think that this is a reasonable concern when giving Kool-Aid to children? Why or why not? Note: Is it a reasonable amount to drink? Do you believe the FDA?

The value of crotonic acid is 2.04 x 10^-5

mare 550 ml of 0,420 M Mg. COH)2 SOlunon?

20.00mL of 6M HCl is taken from 500mL bottle containing the acid and is transferred to 250mL volumetric flask  and diluted to volume with water. What is the molarity of the new solution? Do not enter units with your answer.

A sample weighing 10.91 g containing an unknown amount of H3PO4 was diluted with water and titrated with a standardized concentration of 0.7255 M NaOH. The endpoint was reached after 27.03 mL of the titrant was added. What is the % H3PO4 (97.994 g/mole) in the sample?   H3PO4  +  2 NaOH --> Na2HPO4 + 2H2O   ROUND OFF FINAL ANSWER TO FOUR (4) SIG FIGS

The following two solutions are mixed together: 125.0 mL of 0.2798 MPb(C2H3O2)2(aq) and 275.0 of 0.1901 M KCl(aq)Pb(C2H3O2)2(aq) + 2 KCl(aq) → PbCl2(s) + 2 KC2H3O2(aq)Determine the final concentration of K+ and Pb2+ in solution. Assume the volumes areadditive.

A 1.000-g sample of a sweetening agent containing soluble Saccharin (MM=205.17g/mol) was analyzed using the Volhard method as follows: Step 1: Sample was dissolved in distilled water and treated with 10.0 mL of 0.05M AgNO3. Saccharin-Na + Ag+ → Saccharin-Ag (s) + Na+ Step 2: The solid, Saccharin-Ag (s), formed was filtered off and washed with water. The filtrate and washing were collected quantitatively. Step 3: Titration of the filtrate and washings required 4.6 mL of 0.04M KSCN. KSCN + Ag + → AgSCN (s) + K+ Calculate weight % saccharin in the sweetening agent sample.   could you type it out, please

What quantity in moles of precipitate will be formed when 60.5mL of 0.350M AgNO3 is reacted with excess Mgl2 in the following reaction? 2 AgNO3(aq)+Mgl2(aq)= 2Agl(s)+Mg(NO3)2(aq)

You are performing a chloride analysis on a sample of sports drink. You add 44.36 mL aliquot of sports drink into a flask and titrate the sports drink to endpoint of 12.32 mL of AgNO 3 = 0.104 mol/L, what is the concentration of Cl in the juice in ppm?

Use the data below to detemine the % by mass of Fe to TWO decimal places, if a 0.02 M KMNO4 solution was used for the titration. (MM Fe = 56 g/mol) mass of iron compound (g) 0.691 initial buret reading (mL) 0.77 final buret reading (mL) 16.71
