A student is doing an investigation into the masses of different materials of different densities. A cube has edges of length 1.5 cm and a density of 3500 kg/m².
Calculate the mass of the cube.
Please helppp :(((

0.0118125 (kg)

Explanation:

mass = density x volume

First, find the volume of the cube as you're already given the density. You're also given the length of the cube, 1.5 cm. You need to convert this to m since the density's unit is kg/m^2

1.5cm x (1m/100cm) = 0.015m

Since Volume = (length)^3,

Volume of the cube = (0.015)^3

Volume of the cube = 3.375*10^-6

So mass of the cube = (3500)(3.375*10^-6) = 0.0118125 (kg)

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
