If mass of a material is 79 grams and the volume of the material is 15 cm^3, what would the density of the material be?

Hello!

To find the density of any material or object, we would need to use the formula: d = m/V.

The formula d = m/V is saying: density is equal to mass divided by volume.

We are given the mass, which is 79 grams, and the volume, which is 15 cm³. With those values, we can find the density by dividing.

79 grams / 15 cm³ = 5.3 grams/cm³

Therefore, the density of the material is about 5.3 grams/cm³.

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
