What is the density of an unknown metal that has a mass of 158 g and a volume of 20 ml

7.9g/ml

Explanation:

Density is defined as the ratio of mass of a body to its unit volume.

Density = Mass/volume.

Given mass = 158g

Volume = 20ml

Density = 158/20

= 7.9g/ml

The density of the unknown metal is 7.9g/ml

first thing first of the answer is with technology. second thing second thing is that the big bang theory did not happened u see they say it did but what they dont realize is that like dinasures are still a round they might deny it but they and look at these 12 foot human skelteons they find lets see didnt the bible say something about giants. hope this peace.
