Answer:
0.06022 × 10²³ eggs
Explanation:
Given data:
Moles of eggs = 0.01 mol
Number of eggs = ?
Solution:
The given problem will solve by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
The number 6.022 × 10²³ is called Avogadro number.
For example,
1 mole of egg = 6.022 × 10²³ eggs
0.01 mol × 6.022 × 10²³ eggs / 1 mol
0.06022 × 10²³ eggs
Thus in 0.01 moles of eggs have 0.06022 × 10²³ eggs number of eggs.
Answer:B:63.75
Explanation:(5/8 x 63)+(3/8 x 65)=(0.625 x 63)+(0.375 x 65)=63.75
Answer:
C
Explanation:
C) an atom with an atomic number of 18
The hotter an object is, the faster the motion of the molecules inside it. Thus, the heat of an object is the total energy of all the molecular motion inside that object. Temperature, on the other hand, is a measure of the average heat or thermal energy of the molecules in a substance.
