Question

part 2 of 2

1. ml of a 0.85 m solution

$square$ mol nacl
1.2 mol nacl

Explanation:

Step1: Convert volume to liters

$510. \text{ mL} = 510. \times \frac{1\text{ L}}{1000\text{ mL}} = 0.510\text{ L}$

Step2: Calculate moles of NaCl

Moles = Molarity × Volume (L)
$\text{Moles of NaCl} = 0.85\text{ M} \times 0.510\text{ L}$

Step3: Compute final value

$0.85 \times 0.510 = 0.4335 \approx 0.43$

Answer:

0.43 mol NaCl
