Question

Scrieti corect urmatoarele transformari supa modelul dat: 1mol H2O=18G=0,023*10 la puterea 23 molecule H2O
2 moli H2O=..g=...molecule
1 mol CH4=...g=...molecule
10 moli CH4=...g=...molecule
1 kmol CH4=...g=...molecule
VA ROG AJUTATIMA!!
AM NEVOIE URGENT!!!!!!!!!!!

Answer 1

Pentru H20
2 moli H2O...36 g H20...12.044*10 la puterea 23 molecule H20
Pentru CH4
1 mol CH4...16g CH4...6.022*10 la puterea 23 molecule CH4
10 moli CH4...160g CH4...6.022*10 la puterea 24 molecule de CH4
1 Kmol CH4... 16Kg CH4...6.022*10 la puterea 26 molecule CH4
