How many moles of Mg*2 in 6.00 mL of a 6.0N Mg3(PO4)2 Solution ? First we have to convert moles into equivalents Mg3(PO4)2 3 Mg*2 + 2 PO43 1 mol = equivalents 1 mol MP = mol Mg*2 eq mol (6.00 x 10-3 L)(- eq MP (- eq mol Mg*2 mol MP)(- -) = mol Mg*2 mol MP а. 250. b. 100.0 с. 2 d. 30.00 е. 6 f. 24 g. 3 h. 36 i. 18.0 j. 1 k. 6.00 x 10-3 I. 3.60 x 10-2 m. 6.00 x 10-2 n. 5 o. 3.0 x 10-2 p. 1.80 x 10-2 q. 7.65 x 10-10 r. 2.63 S. 7.89 t. 5.26 u. 1012 V. 109 w. 106 х. 103 у. 95.21 z. 10

My teacher says the answer is 0.84 M, but how?

4.84 mL of a dark blue solution with a dye concentration of 15.72 %m/v is diluted to a total volume of 140. mL. What is the new concentration of the solution in units of %m/v? Do not include units in your answer.

sorry, but how do I determine the molarity of total ions? (NaCl) moles: 0.0225 (NaCl) g: 1.30031 (NaCl) (mol/L): 0.445 Standards V1 (mL) V2 (mL) total volume in volumetric flask Molarity of the dilute solution (M) Molarity of total ions (mol/L) Standard 1 10.0 mL of stock 50.0 0.089 M   Standard 2 6.0 mL of stock 50.0 .0534 M   Standard 3 2.0 mL of stock 50.0 .0178   Standard 4 10.0 mL of standard 1 50.0 .0445 M

O Chemical Reactions = Calculating molarity using solute moles 3/5 Bisho A chemist prepares a solution of barium acetate (Ba (CH3CO2)2) by measuring out 28.2 μmol of barium acetate into a 50. mL volumetric flask and filling the flask to the mark with water. Calculate the concentration in mol/L of the chemist's barium acetate solution. Round your answer to 2 significant digits. mol X 15

1-1. The raw water supply for a community contains 18 mg/L total particulate matter. It is to be treated by addition of 60 mg alum (Al2(SO4)3-14H;O) per liter of water treated. Essentially, all the added alum precipi- tates represented by the following reaction: Al2(SO4)3 · 14H20 → 2 Al(OH);(s) + 3So,- + 6H* + 8H2O For a total flow of 7500 m/d, compute the daily alum requirement, the total concentration of suspended sol- ids in the water following alum addition, and the daily load of particulate solids requiring disposal (including both those initially present and those formed during treatment).

When a Vitamin C (ascorbic acid; MM = 176.12 g mol-1) tablet is crushed, dissolved and titrated with 0.0377  M KIO3(aq) to a purple/blue endpoint (given by a starch indicator), the volume of KIO3 used is 40.01 mL.  How many mg of Vitamin C were in the tablet? KIO3(aq) + 5 KI + 6 H+ → 3 I2(aq) + 3 H2O I2 (aq) + ascorbic acid → 2 I- + dehydroascorbic acid
