Answer:
0.004012km
Explanation:
Problem:
Conversion of millimeters(mm) to Kilometers:
value given = 4012mm
Here, we are converting from a submultiple unit to a multiple unit.
Millimeter depicts 10⁻³m and kilometer stands for 10³m
Now, we must find how many exponents will take us from 10⁻³ to 10³
careful examination shows that if we multiply a power of 10⁶ to 10⁻³ it will give a 10³:
i.e 10⁻³ x 10⁶ = 10⁻³⁺⁶ = 10³
Therefore,
10⁶mm = 1km
4,012mm = = 0.004012km
Answer: ,
Explanation:
Temperature of the gas is defined as the degree of hotness or coldness of a body. It is expressed in units like and
These units of temperature are inter convertible.
We are given:
Temperature of the gas =
Converting this unit of temperature into by using conversion factor:
Converting this unit of temperature into by using conversion factor:
Thus the temperature on the Celsius and Kelvin scales are and
respectively.
The relative molecular mass of the gas : 64 g/mol
<h3>Further explanation</h3>Given
Helium rate = 4x an unknown gas
Required
The relative molecular mass of the gas
Solution
Graham's Law
r₁=4 x r₂
r₁ = Helium rate
r₂ = unknown gas rate
M₁= relative molecular mass of Helium = 4 g/mol
M₂ = relative molecular mass of the gas
Input the value :
