An unknown material has a mass of 2.75 g and a volume of 4 cm3. what is the density of the material? round to the nearest tenth. a) 1.7g/cm3 b) 0.6g/cm3 c) 1.5g/cm3 d) 0.7g/cm3

The density of the material is

Option D

Explanation:

Density of any material is defined as the amount of mass present in a specified volume. So density is directly proportional to the mass of the object and inversely proportional to the volume in which the mass is present.

So the density will be calculated as the ratio of mass to the volume. Thus as the mass of the unknown materials is given as 2.75 g present in a volume of , the density will be

Thus,

it would be c. predictability

all three of these explorers explored the midwest and the area around the great lakes, which they subsequently claimed for france.

this was a big portion of territory and expanded new france which before then only consisted of quebec province in northeastern canada
