Question

Сколько молекул содержит 1,5 моль водорода?

Answer 1

A) Дано:
n (H2) = 1.5 моль
__________________
N (H2) = ?

Решение:
N = Na x n
N = 6 x 10 в 23 степени x 1.5 моль = 9 x 10 в 23 степени молекул
Ответ: N (H2) = 9 x 10 в 23 степени молекул

Answer 2

Number of Molecules in 1.5 Moles of Hydrogen

To calculate the number of molecules in 1.5 moles of hydrogen, we can use Avogadro's number, which is approximately 6.022 x 10^23 molecules per mole.

Using Avogadro's number: 1.5 moles of hydrogen contain approximately 9.033 x 10^23 molecules.

This calculation is based on Avogadro's number, which states that one mole of any substance contains approximately 6.022 x 10^23 particles, whether they are atoms, molecules, or formula units.

Therefore, 1.5 moles of hydrogen contain approximately 9.033 x 10^23 molecules
