Ответ:
Ответ:
M ( NaOH ) = 0.160 M
V ( H2SO4) = 17 mL / 1000 => 0.017 L
M ( H2SO4) = ?
number of moles NaOH:
n = M x V = 0.160 x 0.025 => 0.004 moles NaOH
Mole ratio :
2 NaOH + H2SO4 = Na2SO4 + 2 H2O
2 moles NaOH 1 mole H2SO4
0.004 moles NaOH ? moles H2SO4
moles H2SO4 = 0.004 x 1 / 2
= 0.002 moles of H2SO4
M ( H2SO4) = n / V
M = 0.002 / 0.017
= 0.117 M H2SO4
Answer B
hope this helps!
