Question

use the reaction below to answer the question:
$2na + cl_2 \
ightarrow 2nacl$
taylor has 6.0 moles of sodium and excess chlorine. how many grams of nacl can she make?

Explanation:

Step1: Mole ratio of Na to NaCl

From reaction $2Na + Cl_2
ightarrow 2NaCl$, mole ratio $\frac{n_{NaCl}}{n_{Na}} = \frac{2}{2} = 1$

Step2: Calculate moles of NaCl

$n_{NaCl} = n_{Na} = 6.0\ \text{mol}$

Step3: Molar mass of NaCl

$M_{NaCl} = 23.0\ \text{g/mol} + 35.5\ \text{g/mol} = 58.5\ \text{g/mol}$

Step4: Calculate mass of NaCl

$m_{NaCl} = n_{NaCl} \times M_{NaCl} = 6.0\ \text{mol} \times 58.5\ \text{g/mol}$

Answer:

351 grams
