Question

The density of titanium metal is 4.51 g/cm3 at 25 ∘C What mass of titanium displaces 68.6 mL of water at 25 ∘C∘C?

Answer 1

Answer:

The mass of titanium displaces 68.6 mL of water is 309.4 g.

Explanation:

Given that:-

$\rho=4.51\ g/cm^3$

$V=68.6\ mL$

Also, 1 $cm^3$  = 1 mL

So, $V=68.6\ cm^3$

The expression for the calculation of density is shown below as:-

$\rho=\frac{m}{V}$

Using the above expression to calculate the mass as:-

$m={\rho}\times V$

Applying the values to calculate the mass as:-

$m=4.51\ g/cm^3\times 68.6\ cm^3=309.4\ g$

The mass of titanium displaces 68.6 mL of water is 309.4 g.
