A student needs to know the molarity of a sulfuric acid solution. It is an older bottle and most of the label has been rubbed off. She can see that it is 98% sulfuric acid by mass and the density of the solution is 1.84 g/mL. If she knows the molar mass of sulfuric acid (98 g), can she calculate the molarity

Yes

Explanation:

To calculate the molarity of the sulphuric acid, the student only needs to know its percentage by mass, density and molar mass.

Percentage by mass=98%

Molar mass= 98gmol-1

Density= 1.84gmolmL-1

From

Co= 10pd/M

P= percentage by mass

d= density

M= molar mass

Co= 10×98×1.84/98=18.4M

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
