Density
Scelta multipla
A block has a mass of 250 g and a volume of 200 cm^3. Given that the density of water is 1.00 g/cm^3, what is the density of the block?
A
1.00 g/cm^3
B
1.25 g/cm^3
C
2.00 g/cm^3
D
0.80 g/cm^3

Identify the given quantities: mass of the block \(m = 250\ \text{g}\) and volume of the block \(V = 200\ \text{cm}^3\).
Recall the formula for density, which is the ratio of mass to volume:
\(\text{Density} = \frac{\text{Mass}}{\text{Volume}}\)
Substitute the given values into the density formula:
\(\text{Density} = \frac{250\ \text{g}}{200\ \text{cm}^3}\)
Perform the division to find the density value (do not calculate the final number here, just set up the expression).
Compare the calculated density with the density of water (\(1.00\ \text{g/cm}^3\)) to understand if the block is more or less dense than water.
