The amount of matter present in an object is said to be its mass. The standard SI unit of mass is kg that is a kilogram.
The other units are (g) grams, ton (t), atomic mass unit (u) etc. which are interconvertible.
The name of the mass that is smaller than a gram is microgram. As,
.
Copper has a FCC i.e. face centered cubic crystal structure. The 100 plane is essentially a planar section of the cubic cell where 4 Cu atoms occupy the 4 corners of the plane along with 1 Cu atom at the center of that plane. Each of the Cu atoms in the corners is shared by 4 adjacent unit cells. Thus, there are 2 Cu atoms present in the 100 plane (4*1/4 + 1 = 2).
Now, the planar density PD along the 100 plane is given as:
PD(100) = # atoms in the 100 plane/Area of 100 plane
=
Here R = radius = 0.128 nm =
PD =
Answer:
Explanation:
Hello,
In this case, for computing the atom percent, one must obtain the number of atoms of silver, gold and copper as shown below:
Thus, the atom percent turns out:
Best regards.
