From the graph of Density vs. Concentration (attached), created in Graph 1, what was the relationship between the concentration of the sugar solution and the density of the sugar solution?

What is the molarity (M) of NaCl in a solution in which 5.00 grams of NaCl is dissolved in 800. mL of water? What would be the concentration in units of mM?

You are given a 0.1 M stock solution of glycine. From this stock solution, you are asked to make exactly 150 mL of a 50 μM solution. How would you go about making this solution? Show your unit conversions step by step

Using molarity to find solute moles and solution volume Calculate the volume in milliliters of a 1.31M iron(III) bromide solution that contains 175. mmol of iron(III) bromide (FeBr3). Round your answer to 3 significant digits. mL x10 X 1/5 Ś

A:If 100 mL of a 0.15 M Mg(NO3)2(aq) solution has a density of 1.09 g/mL, which of the following statements is false? Group of answer choices The mass of Mg(NO3)2 in this solution can be determined from this information. If the solution density was not given, it is usually reasonable to assume 1.00 g/mL The mass of the water in this solution is 109 g It is possible to determine the mole fraction of water in this solution.   B: In the body, cell membranes act like semipermeable membranes discussed in class.  If a red blood cell is surrounded by fluid with a higher electrolyte concentration than what is inside the cell, which of the following statements is true? Group of answer choices The cell will shrink because water will pass from the inside of the cell to the fluid The surrounding fluid has a lower osmotic pressure than what is inside the cell The cell will swell up because water will pass from the fluid to the inside of the cell Nothing will happen to the…

4.87 mL of a dark solution with a dye concentration of 15.86 %m/v is diluted to a total  volume of 146. mL. what is the new concentration of solution in %m/v ?

Rearrange this equation to solve for the molecular weight of a compound, assuming you know the mass of solute added. (Triangle) Tf = i x Kf x m

How many grams of copper sulfate would you need to make 4 L of a 6 M copper sulfate solution (m.w. = 160.0 g/mol)? Report your answer in the requested units. Do not report the units in your answer; enter the numbers only. It is recommended that you do not round between calculation steps.

Assuming the volume of a pink freezer pop solution is 30.0 ml and the concentration of red pop is 3.03 g/L, calculate the mass of Red 40 in milligrams in one pink freezer pop.

The EPA limit for manganese in drinking water is 0.05 mg per L of solution. What is this concentration of manganese in mass %, ppb, and molarity? Assume the solution has the same density as water. Use "E" for scientific notation; e.g. 0.001 would be entered 1E-3 mass % ppm molarity = 2.jpg 3.jpg Open file 4.jpg Open file 5.jpg Open file Open file file 99+ op
