Concept explainers
(a)
Interpretation:
The mass of glucose is to be calculated.
Concept introduction:
Molarity is defined as the number of moles of solute that are dissolved in one litre of solution. It is represented by
The formula to calculate the molarity of the solution is as follows:
(b)
Interpretation:
The molarity of isotonic saline is to be calculated.
Concept introduction:
Molarity is defined as the number of moles of solute that are dissolved in one litre of solution. It is represented by
Tonicity is defined as the relative concentration of solutes dissolved in the solution that determines the direction and the extent of flow of particles. Two solutions are said to be isotonic if they have the same concentration.
(c)
Interpretation:
The mass of
Concept introduction:
Molarity is defined as the number of moles of solute that are dissolved in one litre of solution. It is represented by
The formula to calculate the molarity of the solution is as follows:

- The U. S. Environmental Protection Agency (EPA) sets limits on healthful levels of air pollutants. The maximum level that the EPA considers safe for lead air pollution is 1.5 μg/m³ Part A If your lungs were filled with air containing this level of lead, how many lead atoms would be in your lungs? (Assume a total lung volume of 5.40 L.) ΜΕ ΑΣΦ = 2.35 1013 ? atoms ! Check your rounding. Your final answer should be rounded to 2 significant figures in the last step. No credit lost. Try again.arrow_forwardY= - 0.039 (14.01) + 0.7949arrow_forwardSuppose 1.76 g of magnesium acetate (Mg (CH3CO2)2) are dissolved in 140. mL of water. Find the composition of the resulting electrolyte solution. In particular, list the chemical symbols (including any charge) of each dissolved ion in the table below. List only one ion per row. mEq Then, calculate the concentration of each ion in dwrite the concentration in the second column of each row. Be sure you round your answers to the L correct number of significant digits. ion Add Row mEq L x 5arrow_forward
- A pdf file of your hand drawn, stepwise mechanisms for the reactions. For each reaction in the assignment, you must write each mechanism three times (there are 10 reactions, so 30 mechanisms). (A) do the work on a tablet and save as a pdf., it is expected to write each mechanism out and NOT copy and paste the mechanism after writing it just once. Everything should be drawn out stepwise and every bond that is formed and broken in the process of the reaction, and is expected to see all relevant lone pair electrons and curved arrows.arrow_forwardNonearrow_forwardNonearrow_forward
- Draw the structure of the product of the reaction given the IR and MS data. Spectral analysis of the product reveals: MS: M 150, M-15, M-43 CH.COCI AICI, IR: 3150-3000 cm, 2950-2850 cm and 1700 cmarrow_forwardPart II.
