The density of gold is 19.3 g/cm3. What is the volume of a 13 g gold nugget? (Density: D = ) .25 cm3 .67 cm3 1.48 cm3 2.50 cm3
zhannawk [14.2K]

Answer:

<h3>The answer is 0.67 cm³ </h3>

Explanation:

Density of a substance can be found by using the formula

<h3>Density =  \frac{mass}{volume}</h3>

Making volume the subject we have

<h3>volume =  \frac{mass}{Density}</h3>

From the question

mass of gold nugget = 13 g

Density = 19.3 g/cm³

Substitute the values into the above formula and solve for the volume

We have

<h3>volume  =  \frac{13}{19.3}</h3>

= 0.673575

We have the final answer as

<h2>0.67 cm³</h2>

Hope this helps you
