5.6 × 10⁻³ g/mol of C₆H₁₂O₆ are in 1. 90 x 10²² molecules.
The mass per unit amount of a certain chemical entity is known as the molar mass (symbol M, SI unit kgmol1). The chemical entity in question should always be identified in accordance with the mole definition.
The number of atoms present in 1 mole of hydrogen is equal to 6.02 × 10²³ known as Avogadro’s number (NA).
The units of molar mass follow its definition; grams per mole. Mathematically, the defining equation of molar mass is
Molar mass = mass/mole = g/mol
180g/mol glucose has = 6.02 × 10²³
x g/mol glucose has = 1.90 × 10 ²²
To find x;
x = 5.6 × 10⁻³ g/mol
Therefore, 5.6 × 10⁻³ g/mol of C₆H₁₂O₆ are in 1. 90 x 10²² molecules.

The strength of electrical forces tells about the size of charge on the object.
<h3>What is infer about the strength of electrical forces?</h3>
The strength of the electric force between two charged objects depends on the amount of charge that each object have and on the distance between the two charges. When the amount of charge gets bigger, the force also gets bigger, and when the distance between the two charges gets larger, the force also gets smaller. Electric forces are the attraction present between two charge bodies.
So we can conclude that The strength of electrical forces tells about the size of charge on the object.

Answer:
0.0451 mol FeCl₂
General Formulas and Concepts:
<u>Chemistry - Atomic Structure</u>
- Reading a Periodic Table
- Using Dimensional Analysis
Explanation:
<u>Step 1: Define</u>
5.72 g FeCl₂
<u>Step 2: Identify Conversions</u>
Molar Mass of Fe - 55.85 g/mol
Molar Mass of Cl - 35.45 g/mol
Molar Mass of FeCl₂ - 55.85 + 2(35.45) = 126.75 g/mol
<u>Step 3: Convert</u>
<u />
= 0.045128 mol FeCl₂
<u>Step 4: Check</u>
<em>We are given 3 sig figs. Follow sig fig rules and round.</em>
0.045128 mol FeCl₂ ≈ 0.0451 mol FeCl₂
Answer:
Organism best adapted to the environment are able to survive in nature!
Explanation:
Suppose there was a green forest but after a volcano eruption all the green colored vegetation is lost and the area turns black . Now some organisms did survive...you have a black rat, and a white rat. You also have vultures flying in sky looking for prey. Overtime, the organism best adapted to environment can reproduce more and survive in nature. In our example, the black rats are the best adapted because their color matches with the environment so the eagles or vultures would have a hard time spotting them, whereas, a white rat in a black environment can be easily spotted so it has less adaptation to the nature.
Explanation:
Molarity is defined as number of moles per liter of solution.
Mathematically, molarity = 
It is given that molarity is 0.0800 M and volume is 50.00 mL or 0.05 L.
molarity = 
0.0800 M = 
no. of moles = 1.6 mol
Therefore, molar mass of cupric sulfate pentahydrate is 249.68 g/mol. So, calculate the mass as follows.
No. of moles = 
mass in grams = 
= 
= 399.488 g
Thus, we can conclude that 399.488 g of cupric sulfate pentahydrate are needed to prepare 50.00 mL of 0.0800M CuSO4× 5H2O.
