Using volumetric flask, 1.00 g naoh was dissolved in water to make 500.0 ml solution. calculate the molarity

Hey there!:

Molar mass NaOH = 39.997 g/mol

Number of moles ( solute )

n = mass / molar mass

n = 1.00 / 39.997

n = 0.0250 moles of NaOH

Volume in liters:

500.0 mL / 1000 => 0.5 L

Therefore:

Molarity = number of moles /  Volume ( L )

Molarity = 0.0250 / 0.5

Molarity = 0.05 M

Hope that helps!

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .
