4. A salvage operator recovered coins believed to be gold. A sample weighed 385.000g and has a volume of 20.0mL. Were the coins

aleksley [76]

Answer:

Gold

Explanation:

We are given that

Mass of sample ,m=385 g

Volume ,V=20mL

We have to find the coin is gold or yellow brass.

We know that

Density= $\frac{Mass}{volume}$

Using the formula

$Density=\frac{385}{20}g/mL$

$Density=19.25g/mL$

$Density\approx 19.3g/mL$

Density of coin=19.3g/mL

Density of gold=19.3g/mL

Hence, the coin is gold.
