a rectangular block of the element barium is 5.00cm long , 3.00cm wide and 1.00cm high and it weighs 52.5g. what is the density of the element barium?

density= mass/volume

density=mass/volume

5.00cm*3.00cm*1.00cm=15.00cm^3 (or 15.00 mL)

52.5g/15.00 mL= 3.50 g/mL

To find the density of an object, you need to know two things: its mass and its volume. In this case, you have the mass of the barium block, which is 52.5g.

To find the volume of the rectangular bar, you can use the formula:
Volume = Length x Width x Height.

Given the dimensions of the barium block:
Length = 5.00 cm.
Width = 3.00 cm.
Height = 1.00 cm.

You can substitute these values into the formula to calculate the volume:
Volume = 5.00 cm x 3.00 cm x 1.00 cm.

Multiply these values together:
Volume = 15.00 cm³.

Now that we have both the mass and the volume, you can calculate the density using the formula:
Density = Mass / Volume.

Substitute the values:
Density = 52.5g / 15.00 cm³.

Divide the mass by the volume to find the density:
Density = 3.50 g/cm³.

Therefore, the density of the element barium is 3.50 g/cm³.
