The density of each half of the coin is 10.49 g/cm3
In science density is defined as the ratio of mass to volume of an object.
Density is an intrinsic property.It is not affect by the amount of substance present.
This implies that each half of the broken coin must have the same density since it it is an inherent property of every silver material.
The density of each part of the coin therefore is 10.49 g/cm3.

Answer:
0.583 kilojoules
Explanation:
The amount of heat required to pop a single kernel can be calculated using the formula as follows:
Q = m × c × ∆T
Where;
Q = amount of heat (J)
m = mass of water (g)
c = specific heat capacity of water (4.184 J/g°C)
∆T = change in temperature
From the given information, m = 0.905 g, initial temperature (room temperature) = 21°C , final temperature = 175°C, Q = ?
Q = m × c × ∆T
Q = 0.905 × 4.184 × (175°C - 21°C)
Q = 3.786 × 154
Q = 583.044 Joules
In kilojoules i.e. we divide by 1000, the amount of heat is:
= 583.04/1000
= 0.583 kilojoules
