Answer:
0.917 L
Explanation:
Step 1: Given data
Molar concentration of the solution (M): 0.530 M (0.530 mol/L)Mass of Ca(OH)₂ (solute): 36.0 gStep 2: Calculate the moles corresponding to 36.0 g of Ca(OH)₂
The molar mass of Ca(OH)₂ is 74.09 g/mol.
36.0 g × 1 mol/74.09 g = 0.486 mol
Step 3: Calculate the volume of the solution
Molarity is equal to the moles of solute divided by the liters of solution.
M = moles of solute / liters of solution
liters of solution = moles of solute / M
liters of solution = 0.486 mol / (0.530 mol/L) = 0.917 L
Answer:
0.917 liters

Quinine in a 1.664-g antimalarial tablet was dissolved in sufficient 0.10 M to give 500 mL of solution. A 15.00-mL aliquot was then diluted to 100.0 mL with the acid. The fluorescence intensity for the diluted sample at 347.5 nm provided a reading of 327 on an arbitrary scale. A standard 100 ppm quinine solution registered 180 when measured under conditions identical to those for the diluted sample. Calculate the mass of quinine in milligrams in the tablet.
Answers
Answer:
605.6mg of quinine
Explanation:
Based on Lambert-Beer's law, the intensity of an optical measurement is directely proportional to its concentration.
Unknown concentration gives a reading of 327
100 ppm gives 180 of intensity
The concentration of the diluted quinine tablet is:
327 * (100ppm / 180) = 181.67 ppm. The final dilution
The concentration of the first diluted solution is:
181.67 ppm * (100.0mL / 15mL) = 1211ppm
ppm could be defined as mass of solute (In this case of quinine) in mg per liter of solution. That is:
1211mg / L
As the tablet was diluted to 500mL = 0.5L, the mass of the quinine is:
0.5L * (1211mg / L) =

How many moles of water are produced from the reaction of 0.224 mol oxygen according to this equation? 2H2 + O2 -> 2H2O
Answers
Answer:
0.448 mols
Explanation:
Use balanced equation:
2H2 + O2 -> 2H2O
For every one mole of oxygen, there are two moles of water
hence the molar ratio 1:2
So if there are 0.224 mols of oxygen
Water = 0.224×2
Which is 0.448 mols of H20
