Which of the following is a correct measurement of density?
Exam
A. 2.95 centimeters/cubic gram
B. 2.95 grams/pound
C. 2.95 grams/cubic centimeter
D. 2.95 cubic grams/centimeter

C. 2.95 grams/cubic centimeter

Explanation:

Density can be defined as mass all over the volume of an object.

Simply stated, density is mass per unit volume of an object.

Mathematically, density is given by the equation;

The standard unit for the measurement of density of a substance is either kilograms per cubic meters or grams per cubic centimeters.

Hence, 2.95 grams/cubic centimeter is a correct measurement of density

answer: 802.3 kilo joules of energy represents 191.75 kilo calorie of energy.

explanation:

energy released during combustion of one mole methane = 802.3 kilo joules

if 1 kilo joule = 0.239006   kilo calorie

then ,802.3 kilo joule will be = 802.30.239006 kilo calorie

802.3 kilo joule = 191.75 kilo calorie

hence, the energy in kilo calorie is 191.75 kilo calorie.

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
