Question

Cassandra finds a treasure chest packed with metallic coins. The chest has a volume of 0.25m^3. The coins have a combined mass of 4825 kg. Hoping to find gold she calculates the density to determine the metal of the coins.what kind of metal are the coins made of ?
A)bronze (8700kg/m^3)
B)silver(10,500 kg/m^3)
C)lead (11,300kg/m^3)
D)gold (19,300kg/m^3)

Answer 1

Answer:

Option D)gold (19,300kg/m^3)

Step-by-step explanation:

we know that

The density is equal to divide the mass by the volume

so

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

we have

$m=4,825\ kg\\V=0.25\ m^3$

substitute

$D=\frac{4,825}{0.25}$

$D=19,300\ \frac{kg}{m^3}$
