(a)
Interpretation:
The volume of ethanol in liters that needs to be dissolved in water to produce 200.0 L of 1.65 M solution.
Concept introduction:
Number of moles of solute dissolved in one liter of solution is called molarity of solution.
It is mathematically represented as follows:
Here, n is number of moles of solute and V is volume in L.
The number of moles of a substance is related to its mass as follows:
Here, m is mass and M is molar mass.
The density of a solution is calculated using the following formula:
Here, m is mass and V is volume.
(b)

- Citric acid, which can be obtained from lemon juice, has the molecular formula C6H8O7. A 0.250-g sample of citric acid dissolved in 25.0 mL of water requires 37.2 mL of 0.105 M NaOH for complete neutralization. What number of acidic hydrogens per molecule does citric acid have?arrow_forward39. Standard solutions of calcium ion used to test for water hardness are prepared by dissolving pure calcium carbonate. CaCO3, in dilute hydrochloric acid. A 1.745-g sample of CaCO3 is placed in a 250.O-mL volumetric flask and dissolved in HCI. Then the solution is diluted to the calibration mark of the volumetric flask. Calculate the resulting molarity of calcium ion.arrow_forward94. Baking soda (sodium hydrogen carbonate. NaHCO3) is often used to neutralize spills of acids on the benchtop in the laboratory. What mass of NaHCO3 would be needed to neutralize a spill consisting of 25.2 mL of 6.01 M hydrochloric acid solution?arrow_forward
