Question

1. here is the summary of the two solids remaining if reaction #2 occurs when baking soda decomposes.

substance	na	c
solid remaining	? grams na	? grams c

calculate the total mass of solid that would be produced if reaction #2 occurs.
total mass = mass na + mass c

i need a hint
g
the answer to this question depends on your answers to previous questions.

Explanation:

Step1: Calculate mass of Na

Use $m = n \times M$, where $M_{\text{Na}}=22.99\ \text{g/mol}$
$\text{Mass of Na} = 0.0777\ \text{mol} \times 22.99\ \text{g/mol} \approx 1.786\ \text{g}$

Step2: Calculate mass of C

Use $m = n \times M$, where $M_{\text{C}}=12.01\ \text{g/mol}$
$\text{Mass of C} = 0.0777\ \text{mol} \times 12.01\ \text{g/mol} \approx 0.933\ \text{g}$

Step3: Calculate total solid mass

Sum the two masses
$\text{Total mass} = 1.786\ \text{g} + 0.933\ \text{g}$

Answer:

Solid Remaining:

Na: 1.79 g
C: 0.933 g

Total mass of solid produced: 2.72 g
