Particles are measured in atomic mass units, or AMU.
Answer:
1) D. Dissolved Molecule
2) C. 11.30 M
Explanation:
<u><em>Q1:</em></u>
- Glucose (C₆H₁₂O₆) is a non-polar molecule.
- When it is dissolved in water, it will be a dissolved molecule.
- It can not be ionized in water.
- So, the right choice is: <em>D. Dissolved molecule.</em>
<u><em>Q2</em></u>:
- The molarity is the no. of moles of dissolved solute in a 1.0 L of the solution.
<em>M = (n)solute (1000/V (mL) of the solution)</em>
n of LiCl = 2.60 mol, V = 230.0 mL.
∴ M = (n)solute (1000/V (mL) of the solution) = (2.60 mol)(1000)/(230.0 mL) = 11.30 M.
The steps of an experiment are called the Scientific Method. The steps are:
1. Ask a Question
2. Research
3. Construct a Hypothesis
4. Test your Hypothesis (Experiment)
5. Analyze your Data
6. Draw your Conclusion
Here's your answer :)
C7H6O3 (Salicylic acid) + C4H6O3 (Ethanoic anhydride) => C9H8O4 (Aspirin) + C2H4O2 (Acetic acid)
3.54 g / 138.12 g·C7H6O3 mol−1 = 0.0256 moles C7H6O3.
From eqn, 1 mole C7H6O3 reacts with 1 mole C4H6O3 so 0.0256 moles C4H6O3 reacted.
Mass acetic anhydride needed = 0.0256 mol * 102.0886 g mol-1 = 2.61 g (to 3 sig fig).
