The density of gold is approximately 19.2 g/cm3. What is the mass of a sample of gold that displaces 20.0 cm3 of water? Round your answer to the correct number of significant figures.
Density = 19.2 g/cm³
Volume = 20.0 cm³
Mass = ?
D = m / V
19.2 = m / 20.0
m = 19.2 x 20.0
m = 384.0 g
hope this helps!
Answer:
384.0 grams is the mass of a sample of gold that displaces 20.0 \(cm^3\) of water.
Explanation:
Density of gold = \(d=19.2 g/cm^3\)
Volume of water displaced gold = \(20.0 cm^3\)
Volume of water displaced is equal to the volume occupied by the gold sample.
Volume of the gold , v = \(20.0 cm^3\)
\(Density =\frac{Mass}{Volume}\)
Mass of gold :
\(Density\time Volume =19.2 g/cm^3\times 20.0 cm^3= 384.0 g\)
Mass of gold = 384.0 g
