Question

the density of an object has the equation $d = \frac{m}{v}$. if an object has a mass of 2.5 g and a volume of 1.3 cm³, what is its density?

a. 0.52 g/cm³
b. 3.8 g/cm³
c. 1.92 g/cm³
d. 1.2 g/cm³

Explanation:

Step1: Substitute values into formula

Given \(d=\frac{m}{V}\), \(m = 2.5\space g\), \(V=1.3\space cm^{3}\). So \(d=\frac{2.5}{1.3}\).

Step2: Calculate the value

\(\frac{2.5}{1.3}\approx1.92\) (rounded to two decimal places).

Answer:

C. \(1.92\space g/cm^{3}\)
