34.1 mg NaCl in 117.3 mL of solution

Chemistry
1 answer:
Solnce55 [7]2 years ago
6 0

The molarity of the solution will be 4.97 M.

<h3>What is molarity?</h3>

It is the number of moles of solutes per 1 liter of solvent or solution.

Mole of 34.1 g NaCl = 34.1/58.44 = 0.5835 mol

117.3 mL = 117.3/1000 = 0.1173 L

Molarity of the solution = 0.5835/0.1173 = 4.97 M

4NH3+5O2=4NO+6H20 if 32.5 grams of NH3 react with enough oxygen, how many grams of water should form?
Aneli [31]

51.3 gram of water should form if 32.5 g of NH₃ react with enough oxygen.

<h3>How to find the Number of moles ?</h3>

To calculate the number of moles use the formula

Number of moles = \frac{\text{Given Mass}}{\text{Molar Mass}}

                              = \frac{32.5}{17}

                              = 1.9 mol

4NH₃ + 5O₂ → 4NO + 6H₂O

4 mol of NH₃ react with oxygen to given 6 mole of water.

So 1.9 mol of NH₃ produces = \frac{1.9}{4}\times 6

                                              = 2.85 mol of water

Mass of water = Molar Mass of water × Number of moles of water

                        = 18 × 2.85

                        = 51.3 gram

Thus from the above conclusion we can say that 51.3 gram of water should form if 32.5 g of NH₃ react with enough oxygen.

What is the mass number of an ion with 108 electrons, 157 neutrons, and a 1 charge?
levacccp [35]
The answer is 264.12

The element is Bh (Bohrium). If the ion has a 1 charge, the charge can either be 1+ or 1-. So the ion has to be an element with the atomic number 107 or 109 (Bh or Mt). Using simple math, subtract the atomic number from the mass number to equal 157.

264 - 107 = 157

The element that can act like a metal when it is under tremendous pressure and is probably responsible for Jupiter and Saturn's
erastova [34]

Answer:

1. Hydrogen

Explanation:

These planets contain liquid hydrogen in their interior, while the earth has liquid iron in it.

When liquid hydrogen is in tremendous pressure enviroments, the electrons  that make up each atom of this element end up "jumping" to other atoms. These "jumps" allow liquid hydrogen to behave like a metal.

In addition, with the constant energy released by the nucleus of planets like Jupiter and Saturn, as well as their rotations, the liquid hydrogen receives induction of currents, giving rise to extremely powerful magnetic fields.
