19. A sample of an element has a volume of 78.0 mL and a density of 1.85 g/mL. What is the mass in grams of the sample? identify the information you are given. A. 42.2 g
B. 76.2 g
sC. 144 g

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

From the question

volume = 78.0 mL

density = 1.85 g/mL

We have

mass = 78 × 1.85 = 144.3

We have the final answer as

Hope this helps you

if the forces acting on an object are unbalanced, the object will accelerate in the direction of the net force on the object.

explanation:

this is best explained by having an understanding of newton's second law, which states that f=ma. you see, when the forces are unbalanced, net force (sum of all forces) is not zero. therefore making it necessary for the object to have an acceleration in the direction of the net force.

e) none of the above answers are correct
