Question

В стакан налили воду массой 200 г какое понадобится время для того чтобы освободить стакан от воды вынимая по одной молекуле в 1 сек. Дайте подробный ответ пожалуйста.

Answer 1

Відповідь:

66,9*10²³

Пояснення:

m=200 г= 0.2кг

Μ=2*1+16= 18 гр/моль

υ =m/M=200/18=11.1моль

В 1 моле есть 6,02*10²³ молекул

За одну секунду вылетает 1молекула, то  11,1* 6,02*10²³=66,9*10²³  молекул вилетит за 66,9*10²³с

Answer 2

Calculating Time to Remove Water Molecules from a Glass

To calculate the time required to remove water molecules from a glass, we can use the concept of Avogadro's number and the molar mass of water.

Step 1: Calculate the Number of Water Molecules The molar mass of water is approximately 18 grams per mole. Therefore, 200 grams of water is equal to: ``` 200 grams / 18 grams per mole = 11.11 moles of water ```

Each mole contains approximately 6.022 x 10^23 molecules (Avogadro's number). Therefore, the total number of water molecules in 200 grams of water is: ``` 11.11 moles * 6.022 x 10^23 molecules per mole = 6.69 x 10^24 molecules ```

Step 2: Calculate the Time If we remove one water molecule per second, the time required to remove all the water molecules can be calculated as: ``` 6.69 x 10^24 molecules / 1 molecule per second = 6.69 x 10^24 seconds ```

This is an extremely large amount of time. To put it in perspective, it's much longer than the age of the universe.

Therefore, the time required to remove all the water molecules from the glass, removing one molecule per second, is approximately 6.69 x 10^24 seconds.
