Question

Сколько молекул содержится в 2 моль азота, углекислого газа?

Answer 1

1 моль любого вещества содержит 6*10^23 молекул,здесь 2 моль, значит в них содержатся 6*10^23*2=12*10^23 молекул

Answer 2

Calculating the Number of Molecules in 2 Moles of Nitrogen and Carbon Dioxide

To calculate the number of molecules in 2 moles of nitrogen and carbon dioxide, we can use Avogadro's number, which is approximately 6.022 x 10^23 molecules per mole.

Number of Molecules in 2 Moles of Nitrogen: To find the number of molecules in 2 moles of nitrogen, we can use the formula: \[ \text{Number of molecules} = \text{Number of moles} \times \text{Avogadro's number} \]

Using this formula, the number of molecules in 2 moles of nitrogen can be calculated as: \[ \text{Number of molecules} = 2 \times 6.022 \times 10^{23} \]

The result is approximately 1.2044 x 10^24 molecules of nitrogen.

Number of Molecules in 2 Moles of Carbon Dioxide: Similarly, to find the number of molecules in 2 moles of carbon dioxide, we can use the same formula: \[ \text{Number of molecules} = \text{Number of moles} \times \text{Avogadro's number} \]

Using this formula, the number of molecules in 2 moles of carbon dioxide can be calculated as: \[ \text{Number of molecules} = 2 \times 6.022 \times 10^{23} \]

The result is approximately 1.2044 x 10^24 molecules of carbon dioxide.
