What is the concentration, in units of grams of dye per liter of solution (g/L), of the dilute dye solution that is produced as follows? Transfer 16.51 mL of the stock solution (6.12 g/L) to a 200.0 mL volumetric flask and dilute to the 200.0 mL line with deionized water. Your answer should be reported to the correct number of significant figures.

Assume household vinegar contains 5% acetic acid by weight and that the density of vinegar is the same as the density of water (1.00 g/mL). What volume of vinegar would be required to react fully with this amount (5.00 g) of sodium bicarbonate?

A student sets up the following equation to solve a problem in solution stoichiometry. (The ? stands for a number the student is going to calculate.) Enter the units of the student's answer. - 3 mol L ( 27 000) (10 - 1²+) (₁14² - - - - - - g 8.7 83.48 = L mL mol x10 X 3 μ 00 3

An analytical chemist weighs out 0.170 g of an unknown diprotic acid into a 250 mL volumetric flask and dilutes to the mark with distilled water. She then titrates this solution with 0.1200M NaOH solution. When the titration reaches the equivalence point, the chemist finds she has added 21.1 mL of NaOH solution. Calculate the molar mass of the unknown acid. Round your answer to 3 significant digits. 0 g mol 0x x10 X S

Part A Constants I Periodic A 0.5880 g sample of impure magnesium hydroxide is dissolved in 102.0 mL of 0.2044 M HCl solution. The excess acid then needs 19.88 mL of 0.1039 M NaOH for neutralization. Calculate the percent by mass of magnesium hydroxide in the sample, assuming that it is the only substance reacting with the HCl solution. Express your answer using four significant figures.

Please help me answer questions 1 and 2. (Questions attached below) 1. When you arrive at the lab, 2.0 M H2SO4(aq) and 2.0 M HC2H3O2(aq) will be present. Youwill need to dilute these solutions using beakers and graduated cylinders from your drawerand DI water.i. Calculate the volume of the 2.0 M HC2H3O2(aq) and DI water needed to create 50.0 mLof 1.05 M HC2H3O2(aq).ii. Calculate the volume of the 2.0 M H2SO4(aq) and DI water needed to create 50.0 mL of0.75 M H2SO4(aq). 2. A 48.33-mL sample of 0.150 M NaBr is titrated into 50.00 mL of 0.145 M AgNO3. Bothsolutions had the same initial and final temperatures. The reaction occurred in a calorimeterwith a known heat capacity and produced 1546.03 J of heat.i. Write a balanced equation that is occurring.ii. Determine the theoretical yield of the solid.iii. Calculate the enthalpy of the reaction (kJ/mole of precipitate).

A solution is prepared by dissolving 72.91 g of CdCl2 (MM = 183.317) in enough water to make 158.95 mL of solution. If the density of the solution is 1.556 g/mL, what is the molarity of the chloride ions, Cl-(aq), in solution? Report your answer using two decimal places.
