A block of wood has a mass of 180 grams it is 10.0cm long, 6.0cm wide and 4.0cm thick what is it’s volume and density
PilotLPTM [1.2K]

Answer:

<h2>Density = 0.75 g/cm³</h2>

Explanation:

Density of a substance is given by

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

From the question

mass of the wood = 180 g

Since the wood is a cuboid we can find the volume using the formula

Volume = length × width × height

From the question

length = 10cm

width = 6 cm

height = 4 cm

Volume = 10 × 6 × 4 = 240 cm³

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

That's

<h3>Density(\rho) =  \frac{180}{240}  \\  =  \frac{3}{4}</h3>

We have the final answer as

<h3>Density = 0.75 g/cm³</h3>

Hope this helps you

What type of chemical reaction is the following: CH4 + O2 ➜ CO2 + H2O
maria [59]

Complete combustion of an alkane (methane)

You're essentially burning CH4 in the excess presence of oxygen gas, which results in the liberation of water and carbon dioxide
