The forensic technician at a crime scene has just prepared a luminol stock solution by adding 15.0 gg of luminol into a total vo
Firdavs [7]

Answer:

1.13 M

Explanation:

Given data

  • Mass of luminol (solute): 15.0 g
  • Volume of solution = volume of water = 75.0 mL = 0.0750 L
  • Molar mass of luminol: 177.16 g/mol

The molarity of the stock solution of luminol is:

M = mass of solute / molar mass of solute × liters of solution

M = 15.0 g / 177.16 g/mol × 0.0750 L

M = 1.13 M

Susan has a beaker with one mole of water and another beaker filled with one mole of hydrogen chloride. Compare the number of mo
lisabon 2012 [21]

Answer:

Ratio is 1:1 ; they have same number of molecules.

Explanation:

One mole of any compound have same number of molecules, irrespective of their chemistry and composition, i.e. 6.022x10^23 . This number is known as Avogadro's Number.

So the beaker with one mole of water contains = 6.022x10^23 molecules ;

and beaker with one mole of Hydrogen chloride = 6.022x10^23 molecules.

The comparative ratio is 1:1.
