Question

Пожалуйста помогите Подсчитайте количество молекул воды в 1 литре

Answer 1

Ответ:

Вот, держи

Объяснение:

В одном литре воды 1000 граммов, их разделить на 18 граммов, результат = 55,56 моль, эту цифру умножить на число Авогадро, равное 6, 22 х 10 в 23 степени, перемножив получим: 3,3336 х 10 в 25 степени - количество молекул в 1 литре воды.

Answer 2

Ответ:

В 1 л воды содержится 3.35×10^25 молекул

Answer 3

Calculating the Number of Water Molecules in 1 Liter

To calculate the number of water molecules in 1 liter, we can use the fact that 1 mole of any substance contains Avogadro's number of molecules, which is approximately 6.022 x 10^23.

Step 1: Calculate the Number of Moles of Water in 1 Liter

The molar volume of any gas at standard temperature and pressure (STP) is 22.4 liters. Since water is a liquid, we'll use its density to calculate the volume of 1 mole of water.

The density of water is approximately 1 gram per milliliter, which is equivalent to 1000 grams per liter. The molar mass of water is approximately 18 grams per mole.

Using the formula: \[ \text{Number of moles} = \frac{\text{Mass}}{\text{Molar mass}} \]

We can calculate the number of moles of water in 1 liter.

Step 2: Calculate the Number of Molecules

Once we have the number of moles, we can use Avogadro's number to calculate the number of water molecules in 1 liter.

Let's perform the calculations:

Step 1: The number of moles of water in 1 liter: \[ \text{Number of moles} = \frac{1000 \, \text{grams}}{18 \, \text{grams/mole}} = \frac{1000}{18} \, \text{moles} \]

Step 2: The number of molecules in 1 mole: \[ \text{Number of molecules} = 6.022 \times 10^{23} \, \text{molecules/mole} \]

Now, we can calculate the total number of water molecules in 1 liter.

Result: The total number of water molecules in 1 liter can be calculated as: \[ \text{Total number of water molecules} = \left(\frac{1000}{18}\right) \times 6.022 \times 10^{23} \, \text{molecules} \]

Let's calculate the result.
