Determine the mass, in grams, of a piece of this metal that has a volume of 15.3 cubic centimeters. Round your answer to the nearest tenth of a gram. Show your work.

Answer 1

1.8g

Explanation:

Answer 2

The first step is to establish the relationship mass and volume from the data given in the table. This can be done using MS Excel (see attached photo).

From the graph,

y= 0.1174 x

Where y=mass in grams, and x is the volume in cm^3

For x = 15.3 cm^3
Mass = 0.1174*15.3 = 1.7962 g

Rounding off to nearest tenth of a gram,
Mass = 1.8 g
