True or for the flash it gave him his speed when it hit something and exploded and gave him the powers from the speed force but that is just nonfiction I would say that is true.

Making solutions is an extremely important component to real-life chemistry. If you make 3.00 L of a solution using 90.0 g of so
kumpel [21]

Answer:

Final concentration of NaOH = 0.75 M

Explanation:

For NaOH :-

Given mass = 90.0 g

Molar mass of NaOH = 39.997 g/mol

The formula for the calculation of moles is shown below:

moles = \frac{Mass\ taken}{Molar\ mass}

Thus,

Moles= \frac{90.0\ g}{39.997\ g/mol}

Moles\ of\ NaOH= 2.2502\ mol

Molarity is defined as the number of moles present in one liter of the solution. It is basically the ratio of the moles of the solute to the liters of the solution.

The expression for the molarity, according to its definition is shown below as:

Molarity=\frac{Moles\ of\ solute}{Volume\ of\ the\ solution}

Where, Volume must be in Liter.

It is denoted by M.

Given, Volume = 3.00 L

So,

Molarity=\frac{2.2502\ mol}{3.00\ L}=0.75\ M

<u>Final concentration of NaOH = 0.75 M</u>

1. If 80.0 ml of 3.00 M HCl is used to make a 100. ml of dilute acid, what is the molarity
Aleonysh [2.5K]

<u>We are given:</u>

M1 = 3 Molar        V1 = 80 mL

M2 = x Molar        V2 = 100 mL

<u>Finding the molarity:</u>

We know that:

M₁V₁ = M₂V₂

where V can be in any units

(3)(80) = (x)(100)

x = 240/100                                          [dividing both sides by 100]

x = 2.4 Molar

Art [367]
Their locations can vary depending on the molecule they are associated with but they are usually in a "cloud " that is on the outside of an atom/molecule and if the atom is unstable the  electrons tend to be located farther away from the atom.
