СО2

n=0.5 моль

Знайти:

N-?

Розв'язання:

m=n*M

N=m*Na/M

M(CO2)=12+32=44

m=0.5*44=22

N=22*6.02*10²³/44=сори нет калькулятора под рукой

Number of Molecules in 1/2 Mole of Carbon Dioxide Gas

To determine the number of molecules in 1/2 mole of carbon dioxide gas, we need to use Avogadro's number, which states that one mole of any substance contains approximately 6.022 x 10^23 particles (atoms, molecules, or ions).

Since we are given 1/2 mole of carbon dioxide gas, we can calculate the number of molecules using the following equation:

Number of molecules = (1/2 mole) x (6.022 x 10^23 molecules/mole)

Calculating this, we get:

Number of molecules = 0.5 x (6.022 x 10^23 molecules/mole)

Therefore, there are approximately 3.011 x 10^23 molecules in 1/2 mole of carbon dioxide gas.

Please note that the search results provided did not contain the exact answer to this question. However, the calculation provided is based on the fundamental concept of Avogadro's number, which is widely accepted in chemistry.
