I'm having difficulty understanding density. I am trying to relate the concept of density to brownies. Should a brownie with baking soda have a higher or lower density compared to a brownie with no baking soda?

Does a thick brownie mean a high or low density?

When it says high density, does that mean a larger number or a small number?

Please help!

Density = Weigh per unit volume.

Unit means one. Therefore, Density = Weight of one volume of a substance. One volume can be 1m^3, 1cm^3, or 1in^3 depending on which unit you are using.

Water has a density of 1 gram per cm^3(1g/cm^3) which means that 1 cm^3 of water weighs 1 gram. If 1 cm^3 of an object weighs only o.5 grams , its' density is 0.5 grams per cm^3(o.5g/cm^3); Therefore, water has the highest density.

If a 10 m^3-object weighs 7 kg, what is its' density? Density = 7kg/10m^3 = 0.7kg/m^3 or 0.7kg/1m ^3.

Jessica, I hope this helps.
