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

2016 g/mL

0.112 g/mL

2.74g/mL

8.96 g/mL

 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.

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.

if you mean hydrogen and oxygen then water is the product
