I suppose that the answer is A
Answer: 97.2223 ml
Explanation:
The rule that we will use to solve this problem is:
M2*V1 = M2*V2 where:
M1 is the initial concentration = 3.5 m
V1 is the initial volume = 0.25 l = 250 ml
M2 is the final concentration = 9 m
V2 is the final volume that we need to find
Substitute with the givens in the above equation to get V2 as follows:
3.5*250 = 9*V2
V2 = <em><u>97.2223 ml</u></em>
Explanation:
Fundamentally the aluminum foil is a rectangular prism. It has a length, a width, and a thickness.
The volume of a rectangular prism is expressed as
If we know the volume and two of the three dimensions, we can rearrange the equation to solve for the thickness.
But we should also be sure to confirm our units.
A liter is defined as 1000 cm^3. Therefore a mL is equal to 1 cm^3.
You should convert the units of measure given in the problem statement such that the units are aligned. For example, 10.0mm will be 1 cm and 12.5m will be 1250 cm. This will give you a height in cm.
In conclusion, modeling is very useful for predicting molecular polarity because chemical bonds among different atoms are generated to equal electrical charges.
<h3>What is molecular polarity?</h3>
Molecular polarity refers to the unequal distribution of electrical charges in the atoms of a molecule.
This unequal distribution leads to the generation of molecular poles (positive and negative) at the ends of the chemical bonds.
In conclusion, modeling is very useful for predicting molecular polarity because chemical bonds among different atoms are generated to equal electrical charges.
