The answer is very probable because of how incredibly small atoms are

Very probable because of how incredibly small atoms are the chances that at least one of the atoms exhaled in your first breath will be in your last breath.

Hydrogen and oxygen always react in a 1:8 ratio by mass to form water. early investigators thought this meant that oxygen was 8 times more massive than hydrogen.

If you say that something is probable, you mean that it is likely to be true or likely to happen.

Everything around us is made up of really tiny molecules. However, such molecules are constructed from much smaller atoms. Then, even smaller protons, neutrons, and electrons are used to build those atoms. Quarks, which are even smaller particles than protons, make up protons.

The smallest unit of substance that may be disassembled without ejecting any electrically charged particles is the atom. The smallest piece of substance that displays an element's distinctive qualities is an atom. As a result, the atom serves as the basic unit of chemistry.

How many grams of NaCl do you need to prepare 200 ml of a 5M solution? The molecular weight of NaCl is 58.4 g/mol. Smol 0.2L-1mo
Butoxors [25]

Answer:

The answer to your question is: 58.4 g of NaCl

Explanation:

Data

Volume = 200 ml = 0.2 l

Concentration = 5M

MW = 58.4 g

mass NaCl = ?

Formula

             Molarity = (# of moles ) / volume

             # of moles = Molarity x volume

             # of moles = 5 x 0.2

             # of moles = 1

              58.4 g ---------------------- 1 mol

              x          ---------------------  1 mol

              x = (1 x 58.4) / 1

             x = 58.4 g of NaCl

Calculate the molarity of a solution consisting of 25.0 g of KOH in 3.00 L of solution.
melomori [17]

Answer:

0.15M

Explanation:

The equation for molarity is M= n/L. Where "M" is Molarity, "n" is the number of moles of solute, and "L" is the total liters in solution.

You need to calculate the number of moles from the given grams. The molar mass of KOH is (39.098+ 16 +1.008)= 56.106g. To calculate the mols of KOH, \frac{25.0g}{1} × \frac{1 mol}{56.106g} = 0.44558... mol, you see that the grams unit cancel out leaving you with mol as the unit.

The volume is given in L already so no need to do any conversion. M= \frac{0.4558mol}{3.00L} = 0.1485M ≈ 0.15M
