Question

Cate molecule de gaz contine un recipient cu un volum de 600 ml cub daca gazul se afla in conditii normale

Answer 1

Hey

Stim ca un mol de gaz (in conditii normale)  ocupa 22.4 l

V = 600 ml = 0.6 l

[ Aplicam regula de 2 simpla ca sa aflam cati moli de gaz se gasesc in reicipient ]

1 mol gaz  ....... 22.4 l

x moli gaz ....... 0.6 l

x = 0.6 / 22.4 = 0.02 moli gaz

[ Din nou,acum pt. a afla cate molecule au 0.6 moli de gaz ]

1 mol gaz ..... 6.022×10²³ molecule

0.6 moli gaz ..... y molecule

y =  0.6 · 6.022×10²³  = 3.61 · 10²³ molecule sunt in recipient
