A graduated cylinder containing 40 mL of water has a total mass of 60 g. A solid object carefully lowered into the graduated cylinder. The level of the water rises to 70 mL. The total mass of the cylinder, water and object is now 95 g what is the mass? volume? and density

The correct answer is -

A) 35 g

B)30 mL

C)1.66666666666667g/ml3

Explanation:

Given:

mass of graduated cylinder containing 40 mL = 60 g

volume of water = 40 ml

increase in the level of water = 70 ml

increase in mass = 95

Solution:

A) mass of object -

increased mass - initial mass

90 - 60 = 35 g

B) volume of object

increased volume - initial volume

70 - 40 = 30 mL

C)  density d=m/v

d=35/30

d=1.66666666666667

i am going to guess that it is co2.

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."
