Question

3 which is the mass of 8 moles of sodium chloride? * (0.5 points) 468 grams 0.137 g/mol 7.3 grams 468 moles

Explanation:

Step1: Find molar mass of NaCl

Sodium (Na) molar mass: $23\ g/mol$, Chlorine (Cl) molar mass: $35.5\ g/mol$.
Molar mass of $\text{NaCl} = 23 + 35.5 = 58.5\ g/mol$.

Step2: Calculate mass from moles

Mass formula: $m = n \times M$, where $n = 8\ mol$, $M = 58.5\ g/mol$.
$m = 8 \times 58.5 = 468\ g$.

Answer:

468 grams
