A sample of a substance has a mass of 7.5 g and a volume of 2.5 cubic centimeters. What is the object’s density? A.) 3 grams per cubic centimeter
B.) 10 grams per cubic centimeter
C.) 0.3 grams per cubic centimeter
D.) 20.44 grams per cubic centimeter

option A is the correct answer .

Explanation:

as density = mass per unit volume

density = 7.5/2.5 = 3 gm / cm³ ..is the answer ...

pls mark my answer as brainlist pl and plz vote

A) d = 3 g/cm³

Explanation:

Given data:

Mass of substance = 7.5 g

Volume of substance = 2.5 cm³

Density of object = ?

Solution:

Formula:

d = m/v

d = density

m = mass

v = volume

by putting values,

d = 7.5 g/ 2.5cm³

d = 3 g/cm³
