Answer: Amount of volume needed in Litres is 0.09L
Explanation:
Given that the concentration in Mol/L =3.67M
Mass of K2SO4 = 57.3g
Molar mass of K2SO4 = 174.01g/mol
From stochiometry,
Mole = Mass/Molar mass
Mole = 57.3/174.01= 0.33mol.
Concentration in mol/L=
Mole/volume
3.67=0.33/volume
Volume= 0.33/3.67
Volume = 0.09L
Therefore the volume of K2SO4 needed is 0.09L
Multiply the number of moles by Avogadro’s constant:
7.4x6.022x10^23
Answer:
D. ionic sodium phosphate (Na3PO4)
Explanation:
Molecule for molecule, the solute that raises the boiling point of water the most is the one that makes the most particles in the solution. Lithium chloride breaks up into two ions (Li+ and Cl-). So does sodium chloride (Na+ and Cl-). Molecular molecules don't break up at all, so sucrose has only 1 particle per molecule. Sodium phosphate makes 4 total particles (3 Na+ ions and 1 PO4^3-). And magnesium bromide would make 3 particles (1 Mg2+ and 2 Br-). So the most is 4.
