What is the molarity of a solution that contains 0.25 mole of solute in 250 milliliters of solution

Chemistry

marta [7]4 years ago

Answer: 1.0 mol/dm3

Explanation:

Given that:

Amount of moles = 0.25 moles

Volume = 250 millliters of solution

Convert milliliters to liters

If 1000 milliliters = 1 liter

250 milliliters = (250/1000) = 0.25 L

Recall that 1 liter = 1dm3

so, 0.25 liters = 0.25 dm3

Now, molarity is calculated by dividing the amount of a substance by the volume of the solution.

i.e Molarity = (Amount in moles/volume in dm3)

Molarity = (0.25 moles / 0.25 dm3)

= 1.0 mol/dm3

Thus, the molarity of the solution is 1.0 mol/dm3

9) A certain atom has 10 electrons, 14 neutrons, and 11 protons. Write the name of this element in isotope notation.​
Dimas [21]

Answer:

²⁵₁₁Na⁺

Explanation:

Details about the atom:

          Number of electrons  = 10 electrons

          Number of neutrons  = 14 neutrons

          Number of protons  = 11 protons

The atomic number of an atom is a good indicator of the type of atom we have been given.

From the subatomic particles, the number of protons is the same as the atomic number.

 Since the number of protons is 11, its atomic number will be 11.

The element with atomic number 11 is sodium, Na.

  To write a complete notation, we also need the mass number;

  Mass number  = number of protons + number of neutrons

  Mass number  = 11 + 14  = 25

 The charge on the atom:

     Charge  = Number of protons  - number of electrons  = 11  - 10  = 1+

The element in isotopic notation is given as;

                  ²⁵₁₁Na⁺
