What is the mass of a ball whose density is 0.250 g/cm3 and whose volume is 200 cm3?

I think the mass is 0.05 kg but not sure plus i don't understand the question

density = mass/volume

so, m = vol*density
m = 0.250 g/cm^3 * 200cm^3 = 50g = 0.05 kg

D x v equal to mass

To find the mass of the ball, we can use the formula:

Mass = Density × Volume

Given:
Density = 0.250 g/cm^3
Volume = 200 cm^3

Substituting the given values into the formula, we have:

Mass = 0.250 g/cm^3 × 200 cm^3

To simplify, we can cancel out the units of cm^3:

Mass = 0.250 g/cm^3 × 200

Now, multiply the values:

Mass = 50 g

Therefore, the mass of the ball is 50 grams, not 0.05 kg.

To find the mass of the ball, you need to use the formula:

Mass = Density * Volume

In this case, the density is given as 0.250 g/cm3, and the volume is given as 200 cm3.

First, you need to convert the density from grams per cubic centimeter (g/cm3) to kilograms per cubic meter (kg/m3). Since 1 g/cm3 is equal to 1000 kg/m3, the density becomes 0.250 * 1000 = 250 kg/m3.

Next, you need to convert the volume from cm3 to m3. Since 1 m3 is equal to 1,000,000 cm3, the volume becomes 200 / 1,000,000 = 0.0002 m3.

Finally, multiply the density by the volume to find the mass:

Mass = Density * Volume

Mass = 250 kg/m3 * 0.0002 m3

Mass = 0.05 kg

So, the mass of the ball is indeed 0.05 kg.
