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=
Using the formula



Density of coin=19.3g/mL
Density of gold=19.3g/mL
Hence, the coin is gold.
I think the answer is non metal
P1/V1=P2/V2
1/22.4=4/x
X=4 multiple by 22.4
V2=89.6L
I think D, because water evaporates. Once it gets hot. Then condensation. I think
