Giải giúp với ạ, tớ cần gấp, cảm ơn nhiều
Cho 6 gam MgO phản ứng vừa đủ với dung dịch HCl 10,95%. Tính C% của chất tan trong dung dịch sau phản ứng?
làm ơn hãy làm giúp tớ với tớ thực sự rất cần ngày mai tớ thi r cảm ơn mng nhiều
$n_{MgO} = 0,15(mol)$
$MgO + 2HCl \to MgCl_2 + H_2O$
$n_{MgCl_2} = n_{MgO} = 0,15(mol)$
$n_{HCl} = 2n_{MgO} = 0,3(mol) \Rightarrow m_{dd\ HCl} = \dfrac{0,3.36,5}{10,95\%} = 100(gam)$
Sau phản ứng :
$m_{dd} = 100 + 6 = 106(gam)$
$C\%_{MgCl_2} = \dfrac{0,3.95}{106}.100\% =26,89\%$
