Answer:
Explanation:
Let recall the crystal structure of CsBr obtains a BCC structure. In a BCC structure, there exist only two atom per cell.
The density d of CsBr in g/cm³ can be calculated by using the formula:
where;
z = 1 mole of CsBr
edge length = 428.7 pm = (4.287 × 10⁻⁸)³ cm
molar mass of CsBr = 212.81 g/mol
avogadro's number = 6.023 × 10²³
Answer:
Density is 7.15 g /mL.
Mass is 445.2 g.
Explanation:
Density:
Density is equal to the mass of substance divided by its volume.
Units:
SI unit of density is Kg/m3.
Other units are given below,
g/cm3, g/mL , kg/L
Formula:
D=m/v
D= density
m=mass
V=volume
Symbol:
The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.
Given data:
Mass of first zinc sample = 210.10 g
Mass of second zinc sample = 235.10 g
Combined volume = 62.3 mL
Density of combined sample ?
Mass of combined sample = ?
Solution:
Mass of combined sample = 210.10 g + 235.10 g = 445.2 g
density = mass / volume
density = 445.2 g / 62.3 mL
density = 7.15 g /mL
Answer:
b i think because i think so
Answer:
We have NH 4 and that's called the ammonium ion it also stays together.
Explanation:
1.5 ms⁻²
Explanation:
We understand that Force is also given as mass * acceleration;
F = Ma
If force is 6N and the mass is 4kg of the object, the a can be evaluated as follows;
6 = 4a
6/4 = a
1.5 = a
= 1.5m/s²
