If you mean carbs, then you don't eat as much pasta and bread and stuff like that. So practically, all of the good stuff. Use techniques. Tell yourself that it will make you thinner if you don't eat it. I also tell myself that I am stronger than this and that food shouldn't control me. It might or might not work for you.
Hope I could help!
Answer:
We can see that at the boiling point, both liquid and gas are in equilibrium with one another. This is true for any applied pressure and boiling point temperature combination. As a result, we see liquid-gas equilibrium for every temperature and pressure combination on the graph in Figure 13.6.
Considering the definition of percentage by mass, the mass percentage of CaCO₃ is 68.59%.
<h3>What is mass percentage</h3>
The percentage by mass expresses the concentration and indicates the amount of mass of solute present in 100 grams of solution.
In other words, the percentage by mass of a component of the solution is defined as the ratio of the mass of the solute to the mass of the solution, expressed as a percentage.
The percentage by mass is calculated as the mass of the solute divided by the mass of the solution, the result of which is multiplied by 100 to give a percentage. This is:
<h3>Mass percentage of CaCO₃</h3>
In this case, you know:
- mass of CaCO₃: 2.62 grams
- mass of limestone: 3.82 grams
Replacing in the definition of mass percentage:
<u><em>mass percentage= 68.59 %</em></u>
Finally, the mass percentage of CaCO₃ is 68.59%.
