Question

Quantas moléculas de H20 são obtidas ao serem consumidas 90 x 10²³ moléculas de 02?? PFV ME AJUDEM!!!!!

Answer 1

$2H_2 + O_2 \Rightarrow 2H_2O\\2 mol - 1 mol - 2 mol\\\\Regra \ de \ tres :\\\\\\1 \ mol -- 2 \ mol\\90\cdot10^{23} - x\\\\x = 180\cdot10^{23}\\\\\boxed{x = 1.8\cdot10^{25}}$
