How many atoms are in 3.5 moles of NaCl?
Ivenika [448]

Answer:

2.11  ×10²⁴ atoms

Explanation:

Given data:

Number of moles of NaCl = 3.5 mol

Number of atoms = ?

Solution:

It is known that 1 mole contain 6.022×10²³ atoms. The number 6.022×10²³ is called Avogadro number.

3.5 mol ×6.022×10²³ atoms / 1 mol

21.1 ×10²³ atoms

2.11  ×10²⁴ atoms

IF 14.07*10^26 molecules of magnesium chloride was produced in the following reaction, how many grams of magnesium reacted?
Wittaler [7]

Answer:

56160grams

Explanation:

First, we need to convert the number of molecules of magnesium chloride (MgCl2) into moles by dividing by Avagadro's number (6.02 × 10^23 molecules)

n = nA ÷ 6.02 × 10^23

n = 14.07 × 10^26 ÷ 6.02 × 10^23

n = 14.07/6.02 × 10^(26-23)

n = 2.34 × 10^3 moles of MgCl2

The balanced reaction given in the question is as follows:

Mg + 2HCl → MgCl2 + H2

If 1 mole of Mg produced 1 mole of MgCl2

Then, 2.34 × 10^3 moles of Mg will also produce 2.34 × 10^3 moles of MgCl2.

Using mole = mass ÷ molar mass (MM)

Molar mass of Mg = 24g/mol

mass = mole × MM

mass = 2.34 × 10^3 × 24

mass = 56.16 × 10^3

mass = 56160grams.
