Find the "density" of a copper sample whose mass is 134.4 grams and whose volume is 15.0mL
Group of answer choices

0.112 g/mL

2.74g/mL

8.96 g/mL

Sagot :

Answer:  8.96 g/mL

Work Shown:

density = mass/volume

density = (134.4 grams)/(15.0 mL)

density = (134.4/15.0) g/mL

density = 8.96 g/mL

This result is to 3 sig figs which is the smaller sig fig count when comparing the original values 134.4 and 15.0; so this means we don't have to do any rounding.
