Answer:

2.63×10²² atoms

Explanation:

From the question given above, the following data were obtained:

Mass of calcium (Ca) = 1.75 g

Number of atoms of calcium (Ca) =?

From Avogadro's hypothesis,

1 mole of Ca = 6.02×10²³ atoms

Recall:

1 mole of Ca = 40 g

Thus,

40 g of Ca = 6.02×10²³ atoms

Finally, we shall determine the number atoms in 1.75 g of calcium. This can be obtained as follow:

From Avogadro's hypothesis,

40 g of Ca = 6.02×10²³ atoms

Therefore,

1.75 g of Ca = 1.75 × 6.02×10²³ / 40

1.75 g of Ca = 2.63×10²² atoms

Thus, 1.75 g of Ca contains 2.63×10²² atoms.

Answer:

$\huge\boxed{n = 3.5\ moles}$

Explanation:

Given :

Mass in grams = m = 42 g

Molar Mass = M = 12

Required:

No. of moles = n = ?

Formula :

m = m / M

Solution:

n = 42 / 12

n = 3.5 moles

bagirrra123 [75]

Answer:

The answer to your question is P1 = 1.4 atm

Explanation:

Data

Volume 1 = V1 = 735 ml

Pressure 1 = P1 = ?

Volume 2 = V2 = 1286 ml

Pressure 2 = P2 = 0.8 atm

Process

To solve this problem use Boyle's law.

P1V1 = P2V2

-Solve for P1

P1 = P2V2 / V1

-Substitution

P1 = (0.8 x 1286) / 735

-Simplification

P1 = 1028.8 / 735

-Result

P1 = 1.4 atm

Predict the charge on the monatomic ions formed from the following atoms in binary ionic compounds in the following order: Magne

Drupady [299]

The charge on the monatomic ions of Magnesium, Aluminum, Strontium, and Nitrogen are +2, +3, +2, and -3.

<h3>What is the charge on the ions of atoms of Magnesium, Aluminum, Strontium, Nitrogen?</h3>

The charge on an ion is due to the valency of the atom.

The charge on the ion shows the number of electrons gained or lost by the atom in order to form an ion.

The charge on an ion depends on the group the element belongs to.

Therefore, the charge on the monatomic ions of Magnesium, Aluminum, Strontium, and Nitrogen are +2, +3, +2, and -3.
