Question

how many moles of H2O are formed on combustion of 23g of ethane?​

Answer 1

Step-by-step explanation:

$C_2H_6 + \frac{7}{2} O_2 - - - ›2CO_2 + 3H_2O \\ n_{C_2H_6} = \frac{23}{30} \: mol \\ 1 \: mol \: of \: C_2H_6 \: produce \: 3 \: mol \: of \: H_2O \\ \frac{23}{30} mol \: of \: C_2H_6 \rightarrow 3 \times \frac{23}{30} \: mol \: of \: H_2O\\ \rightarrow 2.3\: mol \: of \: H_2O \\ \\ \red{\mathfrak{ \large{\underline{{Hope \: It \: Helps \: You}}}}} \\ \blue{\mathfrak{ \large{\underline{{Mark \: Me \: Brainliest}}}}}$
