Answer:
The answer to your question is 71.22 g
Explanation:
Data
Density = 19.3 g/cm³
Volume = 0.00369
mass = ?
Formula
Density = 
Solve for mass
mass = density x volume
Process
1.- Convert volume from liters to cubic centimeters
1 l ---------------- 1000 cm³
0.00369l --------- x
x = (0.00369 x 1000 ) / 1
x = 3.69 cm³
2.- Substitution
mass = 19.3 x 3.69
3.- Simplification and result
mass = 71.22 g
Explanation:
It is known that the maximum value of ml is equal to the vale of l. But the minimum value of n is as follows.
n = l + 1
where, n = principle quantum number
l = azimuthal quantum number
Values of n can be 1, 2, 3, 4 and so on. Whereas the values of l can be 0, 1, 2, 3, and so on.
Also, "m" is known as magnetic quantum number whose values can be equal to -l and +l.
So, when n = 1 then l = 0 and m = 0.
When n = 2 then l = 1 and values of m will be equal to -1, 0, +1. As it is given that the magnetic quantum number ml = -1. Hence, it is only possible when n = 2.
Thus, we can conclude that the smallest possible value of the principal quantum number n of the state is 2.
Occurs at a specific temperature
Answer:
0.42g/cm³ or 420kg/m³
Explanation:
1cm³ = 1ml
10 × 1cm³ = 10cm³
Density = Mass ÷ Volume
4.2g ÷ 10cm = 0.42 g/cm³
Density = 0.42g/cm³ or 420kg/m³
Answer: Option (d) is the correct answer.
Explanation:
Properties that are unable to bring any change in chemical composition of a substance are known as physical properties.
For example, size, shape, volume, density, boiling point, melting point etc is a physical property.
Whereas properties that bring change in chemical composition of a substance are known as chemical properties.
For example, combustion, toxicity, reactivity etc are all chemical properties.
Thus, we can conclude that a physical property is a property the sample displays without changing its composition.
