A block of sodium that has the measurements 3.00 cm x 5.00 cm x 5.00 cm and a mass of 75.5 g. Calculate the density to the correct number of significant figures

Answer :

The density of the sodium block is 1.0067 g/cm³.

First, calculate the volume of the sodium block:

Volume = length * width * height

Volume = 3.00 cm * 5.00 cm * 5.00 cm = 75.0 cm³

Next, calculate the density:

Density = mass / volume

Density = 75.5 g / 75.0 cm³ = 1.0067 g/cm³

Considering significant figures:

The given mass has 4 significant figures (75.5 g).

The given dimensions have 3 significant figures each.
