Answer:
a) 2.01 g
Explanation:
- Na₂CO₃ (s) + 2AgNO₃ (aq) → Ag₂CO₃ (s) + 2NaNO₃
First we <u>convert 0.0302 mol AgNO₃ to Na₂CO₃ moles</u>, in order to <em>calculate how many Na₂CO₃ moles reacted</em>:
- 0.0302 mol AgNO₃ *
= 0.0151 mol Na₂CO₃
So the remaining Na₂CO₃ moles are:
- 0.0340 - 0.0151 = 0.0189 moles Na₂CO₃
Finally we <u>convert Na₂CO₃ moles into grams</u>, using its <em>molar mass</em>:
- 0.0189 moles Na₂CO₃ * 106 g/mol = 2.003 g Na₂CO₃
The closest answer is option a).

Explanation:
Judy Hopps was one of the smaller prey animal while the others were predators or bigger prey animals. Meaning, she was tiny and in some minds, was easier to take down or may not be able to do the job as well as the bigger animals. Also, she was, less noticeably, the only female prey animal.
The density of carbon tetrachloride, given the data is 1.59 g/mL
<h3>What is density? </h3>
The density of a substance is simply defined as the mass of the subtance per unit volume of the substance. Mathematically, it can be expressed as
Density = mass / volume
with the above formula, we can determine the density of carbon tetrachloride. Details below:
<h3>How to determine the density of carbon tetrachloride</h3>
The following data were obtained from the question:
- Mass of flask = 345.8 g
- Mass of flask + carbon tetrachloride = 703.55 g
- Mass of carbon tetrachlorcide = 703.55 - 345.8 = 357.75 g
- Volume of carbon tetrachlorcide = 225 mL
- Density of carbon tetrachlorcide =?
Density = mass / volume
Density of carbon tetrachlorcide = 357.75 / 225
Density of carbon tetrachlorcide = 1.59 g/mL
