410g Ag
2.3*10^24 atoms
1 molcule Ag- 6.02g*10^3
Answer:
The density is 0,5 g/cm3
Explanation:
The density (δ) is the ratio between the mass and the volume of a compound:
δ=m/v= 3 g/6 cm3= <em>0,5 g/cm3</em>
Answer:
The length of a side of the square is 4.53 cm
Explanation:
Volume (V) = mass/density
mass = 3.4 mg = 3.4/1000 = 0.0034 g
density = 19.3 g/cm^3
V = 0.0034/19.3 = 1.76×10^-4 cm^3
Volume = area × thickness
Area = volume/thickness = 1.76×10^-4/8.6×10^-6 = 20.48 cm^2
Length of one side of the square = sqrt(area of square) = sqrt(20.48 cm^2) = 4.53 cm
Answer:
Mass of copper metal will be 2.06756 gram
Explanation:
We have given number of moles of copper n = 0.03256
Molar mass of copper = 63.5 u
We have to calculate mass of copper metals in gram
We know that number of moles is given by 
Mass in gram = 2.06756 gram
So mass of copper metal will be 2.06756 gram
Answer:
A clean energy resource
Nuclear energy originates from the splitting of uranium atoms – a process called fission. This generates heat to produce steam, which is used by a turbine generator to generate electricity. Because nuclear power plants do not burn fuel, they do not produce greenhouse gas emissions.
