Solve correctly using dimensional analysis. Show the complete solution. Do not round off nonfinal answers.

Suppose 0.816g  of barium nitrate is dissolved in  100.mL  of a  42.0mM  aqueous solution of sodium chromate.   Calculate the final molarity of nitrate anion in the solution. You can assume the volume of the solution doesn't change when the barium nitrate is dissolved in it. Be sure your answer has the correct number of significant digits.

A 0.3360 g sample of potassium hydrogen phthalate is dissolved in 100.0 mL of water.

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).

Please help me with this one Sugar is the solute and water is the solvent. The drink mix will be considered negligible and is added simply for the visualization of dilution results. Calculate the concentration of sugar in this solution using the volume percent equation. Refer to the background for sample calculations. For the purpose of this exercise, it can be assumed that the weight of the drink mix is 0.00 g. The volume of the solution is 3 and 1/3 cups. Convert to metric units, then calculate and record the volume percent in Data Table 1 (Note that 1 cup = 236 mL). Volume % = Volume of Solute/ Volume of Solution × 100%

How many liters of 0.250 M NaOH solution can be prepared from 10.0 g of NaOH? Place your answer in the box. Express your answer using only a number without text. Report your result in decimal notation and to the proper number of significant figures. All numbers are measured.

You have a 1:5 dilution. Describe how you would make a 1:100 dilution.

Suppose 47.6 g of potassium iodide is dissolved in 250. mL of a 0.70 M aqueous solution of silver nitrate. Calculate the final molarity of iodide anion in the solution. You can assume the volume of the solution doesn't change when the potassium iodide is dissolved in it. Round your answer to 2 significant digits.
