Question

What volume of a 2.0M NaOH solution would be lethal for a 60kg person?

(LD50 NaOH = 0.0010 mol/kg)

Answer 1

`\boxed{\text{30 mL}}`

Step-by-step explanation:

Step 1. Calculate the moles of NaOH

`n = \text{60.0 kg} * \frac{\text{0.0010 mol}}{\text{1 kg}} = \text{0.0600 mol}`

Step 2. Calculate the volume of NaOH

`V = \text{0.0600 mol} * \frac{\text{1 L}}{\text{2.0 mol}} = \text{0.030 L} = \text{30 mL}\\\\\text{The lethal volume of NaOH is } \boxed{\textbf{30 mL}}`
