Question

I'm super confused. Can anybody answer while writing the steps?

Write a formula showing the dependence of the mass of a piece of cork on its volume, if the density of cork is 0.18g/cm3. Using the formula, find the mass of a piece of cork with a volume of 240 cm3

If the mass of a piece of cork is m, and its volume is v, the formula will be _____
If v = 240 cm3, m = ______

Answer 1

The formula for desnity is d= m/v (mass over volume), so

1) 0.18 = 240/v Plug in the numbers you have (0.18 being the density and 240 being the volume)

2) 0.18(240) = 240/v(240) multiply 240 on each side to get rid of the 240 on the right side of the equation.

3) 43.2 = m

So, the formula would be d=m/v and m= 43.2
