The answer for the following question is explained below.
Therefore the total number of orbitals are " 9 ".
Explanation:
Orbital:
An orbital is a mathematical function that describes the wave-like behavior of an electron,electron pair,or the nucleons.
The total number of orbitals present in the 3rd energy level is 9.
Here,
A 3 s subshell has only one orbital.
A 3 p subshell has three orbitals.
A 3 d subshell has five orbitals.
Therefore the total number of orbitals is:
3 s = 1 orbital
3 p = 3 orbitals
3 d = 5 orbitals
total orbitals in 3rd energy level is = 1 + 3 + 5 =9
Therefore the total number of orbitals are " 9 ".
Answer:
Density rectangular block = 7.47 (Approx) gm/cm³
Explanation:
Given:
Length = 8.335 cm
Width = 1.02 cm
Height = 0.982 cm
Mass = 62.3538 gm
Find:
Density rectangular block
Computation:
Volume of block = lbh
Volume of block = (8.335)(1.02)(0.982)
Volume of block = 8.3486 cm³
Density = Mass / Volume
Density rectangular block = 62.3538 / 8.3486
Density rectangular block = 7.47 (Approx) gm/cm³
Answer:
I hope this helps 52.2 g/mol
Explanation:
1) Solve for the moles using PV = nRT:
n = PV / RT
n = [(700.0 mmHg / 760.0 mmHg atm¯1) (48.0 L)] / [(0.08206 L atm mol¯1 K¯1) (293.0 K)]
n = 1.8388 mol
2) Divide the grams given (96.0) by the moles just calculated above:
96.0 g / 1.8388 mol = 52.2 g/mol
