Just use the equation M=DV which means Mass equals Density times Volume. Simply plug your values into the equation to get
M=.789(139) and solve
Answer:
It is a network solid, a lattice of many covalent bonds (like diamond, except that it is black rather than transparent).
Explanation:
The main characteristics of glass are transparency, heat resistance, pressure, and breakage resistance, and chemical resistance.
"cg" is centigram, which is one-hundredth of a gram.
I will first convert from g to cg (multiply by 100), then from mL to L (multiply by 1000).

Answer:
Silver
Explanation:
Given parameters:
Mass = 116g
Energy = 511J
Initial temperature = 21.6°C
Final temperature = 40.5°C
Unknown:
Specific heat capacity and the type of metal = ?
Solution:
To solve this problem, we need to find the specific heat capacity of the metal given,
H = m x c x Ф
H is the energy
m is the mass
c is the specific heat capacity
Ф is the change in temperature
511 = 116 x c x (40.5 - 21.6)
511 = 2192.4c
c = 0.233J/g°C
The specific heat capacity of silver is similar to this.
