A rock has a mass of 15 grams and a volume of 5 cm3 what is the density of the object

Chemistry
1 answer:
Zina [86]3 years ago
5 0

Answer:

The answer is

<h2>3.0 g/cm³</h2>

Explanation:

To find the density of a substance when given the mass and volume we use the formula

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

From the question

mass = 15 g

volume of rock = 5 cm³

The density of the substance is

density =  \frac{15}{5}

We have the final answer as

<h3>3.0 g/cm³</h3>

Hope this helps you

What is the mass of a bar of aluminum with length 5.3cm, width 0.32 cm and height 2.34cm? The density of aluminum is 2.70g/cm3.
Tatiana [17]

Answer:

<h2>mass = 10.72 g</h2>

Explanation:

Density of a substance can be found by using the formula

Density =  \frac{mass}{volume}

Making mass the subject we have

mass = Density \times volume

From the question

Density = 2.70 g/cm³

We assume that the aluminum is a cuboid

and volume of a cuboid is given by

Volume = length × width × height

length = 5.3 cm

width = 0.32 cm

height = 2.34 cm

Volume = 5.3 × 0.32 × 2.34 = 3.97 cm³

Substitute the values into the above and solve for the mass

We have

mass = 2.70 × 3.97

We have the final answer as

<h3>mass = 10.72 g</h3>

Hope this helps you

Calculate the relative formula/atomic mass of each of the following compounds:
zmey [24]
1. HCl (H:1, Cl 35.5) ---> 1+35.5 = 36.5
2. FeS (Fe:56, S:32) ---> 56+32 = 88
3. Cl2 (Cl:35.5) ---> 35.5 x 2 = 71
4. CaC03 (Ca:40, C: 12, O: 16) ---> 40 + 12 + 3(16) = 100
5. Fe0 (Fe: 56, O: 16) ---> 56+16=72
