Question

A cube of Osmium metal 1.500 cm on a side has a mass of 70.31 g at 25°C. The density of titanium metal is 4.51 g/cm³ at 25°C. What mass of titanium displaces 65.4 mL of water at 25°C? Express your answer using three significant figures.

Answer 1

The mass of titanium that displaces 65.4 mL of water at 25°C is 295 g.

Step-by-step explanation:

To find the mass of titanium that displaces 65.4 mL of water, we can use the density formula: density = mass/volume. Rearranging the formula to solve for mass, we get: mass = density x volume. The density of titanium is 4.51 g/cm³, so we convert the volume from mL to cm³ by dividing it by 1.0. Finally, we calculate the mass by multiplying the density by the volume. The mass of titanium that displaces 65.4 mL of water at 25°C is 295 g.
