<h2>Answer:</h2>
The number of particles in 1 mol of substance is given by the Avogadro's constant. Its value is: = 6.02214076×10²³ mol⁻¹
The definition of Avogadro's constant is:
The Avogadro constant is the proportionality factor that relates the number of constituent particles in a sample with the amount of substance in that sample. Its SI unit is the reciprocal mole, and it is defined exactly as
= 6.02214076×10²³ mol⁻¹. (per mol).
Thus, the number of particles in 1 mol of substance is given by the Avogadro's constant. Its value is: = 6.02214076×10²³ mol⁻¹

Answer:
4.8 inches
Step-by-step explanation:
Given: The largest frog in the world is goliath which is 12 inches long.
The smallest frog is about 2.5 as long as the goliath.
Lets assume the length of smallest frog be "x".
As given, smallest frog is about 2.5 as long as the goliath.
∴ we can form equation as
Solving the equation to find the value of x
Dividing both side by 2.5
⇒
∴
Hence, the length of smallest frog is 4.8 inches.
Answer:
We know that a^2+b^2=c^2. The 45° angle lets us know that y=x (45+45+90=180), so the problem is y^2+x^2=4sqrt of 2
So you get y^2+x^2=32, and from there, since we know x and y are equal, you can just divide 32 by 2 then take the square root of that, so the answer should be <em><u>4</u></em><em><u> </u></em><em><u>for</u></em><em><u> </u></em><em><u>both</u></em><em><u> </u></em><em><u>x</u></em><em><u> </u></em><em><u>and</u></em><em><u> </u></em><em><u>y</u></em>
