80.24% carbon, 9.62% hydrogen and 10.14% oxygen
1) Base: 100 g
C: 80.24 g
H: 9.62 g
O: 10.14 g
----------
100.00 g
2) Conversion to moles
C: 80.24 g / 12.00 g /mol = 6.687 mol
H: 9.62 g / 1.00 g/mol = 9.62 mol
O: 10.14 g / 16.00 g/mol = 0.63375 mol
3) Ratio
C:6.687 / 0.63375 = 10.55
H: 9.62 / 0.63375 = 15.18
O: 0.63375 / 0.63375 = 1
Given that the tenth of C is 0.5 you need to multiply all the numbers by 2 =>
C: 10.55 * 2 = 21.1--> 21
H: 15.18 * 2 = 30.36 -> 30
O: 1 * 2 = 2
=> C21 H30 O2
Answer: C21 H30 O2
The answer is beryllium-10
In the question, the number of atoms per unit cell is required for:
A) Polonium (Po)
In polonium, the structure is simple cubic, meaning there are 8 corner atoms, which add up to one atom per unit cell.
B) Manganese (Mn)
The structure of the Mn can be considered to be a body centered cubic (BCC) and the number of atoms for this is 8 corner atoms and 1 central atoms, making a total of 2 atoms per unit cell.
C) Silver (Ag)
Silver has a face centered cubic (FCC) unit cell structure, where there are 8 corner atoms and 6 atoms on the faces, so there are a total of 4 atoms per unit cell.
Answer:
C
Explanation:
Of course increasing the pressure will reduce the volume
P1V1 = P2V2
P1V1/P2 = V2 WHEN P2 = 2 P1----multiply both sides by 1/2
P1 V1 / 2P1 = 1/2 V2 <===== 1/2 the original
