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?
To calculate the density of an object, you need to divide its mass by its volume. In this case, the mass of the barium block is given as 52.5g. We can find the volume by multiplying the length, width, and height of the block.
So, first, let's calculate the volume of the barium block:
Volume = Length x Width x Height
Volume = 5.00cm x 3.00cm x 1.00cm
Volume = 15.00 cm³
Now that we have the volume and mass, we can calculate the density:
Density = Mass / Volume
Density = 52.5g / 15.00 cm³
Density = 3.50 g/cm³
Therefore, the density of the element barium is 3.50 g/cm³.
