Answer:

i. Molar mass of glucose = 180 g/mol

ii. Amount of glucose = 0.5 mole

Explanation:

<em>The volume of the glucose solution to be prepared</em> = 500 cm^3

<em>Molarity of the glucose solution to be prepared</em> = 1 M

i. Molar mass of glucose (C_1_2H_6O_6) = (6 × 12) + (12 × 1) + (6 × 16) = 180 g/mol

ii.<em> mole = molarity x volume</em>. Hence;

amount (in moles) of the glucose solution to be prepared

                 = 1 x 500/1000 = 0.5 mole

Choose the molecule or compound that exhibits dipole-dipole forces as its strongest intermolecular force.
LuckyWell [14K]

Answer:

SO2

Explanation:

Dipole-Dipole exist between parmanent dipoles in a molecule. THis means that molecule must have a parmanent dipole moment in it.

Example - HCl

Hydrogen bonding is an attraction between lone pair of an electronegative element and H atom of same or different molecule. H must be covalantly attached to either F, N or O.

Example - H2O

Among the molecules given in the list only SO2 and H2O exihibits parmanent moment. As BCl3 , CBr4 and H2 are symmetric compounds.

Since, SO2 cannot exihibit H- bonding only dipole-dipole forces as its strongest intermolecular force.

You have 627 ml of 5.04 M HCl. Using a volumetric pipet, you take 229 ml of that solution and dilute it to 921 ml in a volumetri
trasher [3.6K]

Answer:

0.653

Explanation:

1)

M1V1 = M2V2

M1 = 5.04 M

V1 = 229 mL ( you take only this volume)

V2 = 921 mL

5.04*229 = M2 * 921

M2 = (5.04*229)/921 Molarity

2)

M1V1 = M2V2

M1 = (5.04*229)/921

V1 = 100 mL

V2= 192 mL

(5.04*229)/921 *100 = M2 * 192

M2 = [(5.04*229)/921 *100]/192 = 0.653 final molarity
