Answer:
19) 3.6920 × 10⁻⁵
20) 4.059× 10²
21) 2.46810121416 × 10³
22) 1.0000× 10⁻³
Explanation:
Scientific notation is the way to express the large value in short form.
The number in scientific notation have two parts.
The digits (decimal point will place after first digit)
× 10 ( the power which put the decimal point where it should be)
For example:
0.000036920
In scientific notation = 3.6920 × 10⁻⁵
405.9
In scientific notation = 4.059× 10²
2468.10121416
In scientific notation = 2.46810121416 × 10³
0.0010000
In scientific notation = 1.0000× 10⁻³
It will take the Ne gas approximately 1.2 s to equilibrate between the two sides.
We know that the time taken for a gas to diffuse is dependent on the molar mass of the gas. This is one of the interpretations of Graham's law of diffusion in gases. Thus, Let;
t1 = time taken for Rn to equilibrate = 4.0 s
t2 = time taken for Ne to equilibrate = ?
M1 = molar mass of Rn = 222g/mol
M2 = molar mass of Ne = 20 g/mol
Using
t1/t2 = √M1/M2
4/t2 = √222/20
4/t2 = 3.33
t2 = 4/3.33
t2 = 1.2 seconds
