Answer:
20 g/mol
Explanation:
We can use <em>Graham’s Law of diffusion</em>:
The rate of diffusion (<em>r</em>) of a gas is inversely proportional to the square root of its molar mass (<em>M</em>).
If you have two gases, the ratio of their rates of diffusion is
Squaring both sides, we get
Solve for <em>M</em>₂:
The activity series of metals as well as the electrode potential of metals can be used to compare the reactivity of metals.
<h3>What is used in comparing reactivity of metals?</h3>
The reactivity of metals can be compared using their electrode potentials which is a measures of the ability of the metal to donate electrons to another metal.
When comparing the reactivity of metals, the metal with the lesser negative electrode potential will be more reactive than another with a greater negative or positive electrode potential.
Therefore, the activity series of metals as well as the electrode potential of metals can be used to compare the reactivity of metals.

Answer:
V = 4480.56 cm3
Explanation:
Data Given
Length “l” = 14 inches
Hight “h” = 7 inches
Width “w” = 1.5 feet
Volume= “V”
Solution:
Formula to Use
V= l . w. h
Note: here we have to values in the same unit
So the Length “l” and Hight “h” both are in inches but the width is in feet
So we changes the feet into inches
1 foot = 12 inches
1.5 feet = 12 x 1.5
1.5 feet = 18 inches
So width is 18 inches
Now putting the values in formula
V = l . w. h
V = 14 . 18 . 7
V = 1764 inch
You can convert inches to cm
1 inch = 2.54 cm
So 1764 inches = 2.54 x 1764
1764 inches = 4480.56 cm3
So
V = 4480.56 cm3
