130.0 grams of NaNO 3 is dissolved in water to make a 5.00 L solution. What is the molarity of the solution? (Molar mass of NaNo3 =g/mol) what is the molarity

0.31M

Explanation:

Given parameters:

Mass of NaNO₃  = 130g

Volume of solution  = 5L

Molar mass  of NaNO₃  = 23 + 14 + 3(16) = 85g/mol

Unknown:

Molarity of solution = ?

Solution:

Molarity is one of the ways of expressing concentration.

It is defined as the number of moles in a volume of solution.

 Molarity  =

  let us find the number of moles of NaNO₃;

                Number of moles  =  =  = 1.53moles

Molarity  of solution =   = 0.31M

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.

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.
