41.7 g of a substance are added to a graduated flask containing 523 ml of water The
water level rises to the 56.8 ml mark. From this information, calculate the density and
specific gravity

9.266 gm/ml is the density of the substance. 9.266 is the specific gravity of the substance.

Explanation:

Data given:

mass of the substance = 41.7 grams

initial volume of water = 52.3 ml

volume after adding the substance = 56.8 ml

volume of the metal = 56.8 - 52.3 = 4.5 ml

density =?

specific gravity =?

density is calculated by using the following formula:

density =

            =

density    = 9.266 gm/ml

The ratio of density of the substance with the reference substance density is called specific gravity. In this case the reference substance is water which has density of 1 gm/ml at 4 degrees.

so specific gravity =

         putting values in above equation:

 specific gravity =

                             = 9.266 (no units as both denominator and numerator has same units and got cancelled)

a is the answer to this question

explanation:

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
