A) How many mosm solute will 1 gram of NaCl yield? Show your calculations. (1gNaCl/1)*(1000mg/1gNaCl)(2/58mg)=34.5mOsm. 3. Mixed Solutions: If 1 mmole of glucose (180mg=1mOsm) and 1 mmole of NaCl (58mg=2mmOsm) are put into a beaker and distilled water added to make 1 liter, the osmolarity is 3 mOSm/L.
Royte’s excerpt makes many views of the effects of tap water and the different types of problems associated with drinking it. In many areas, they say it is okay to drink the tap water but there are a few instances where the water needs to be filtered. She explains the different types of bacteria’s in tap water around the United States but she does tell how the bottled water companies do not answer to the public and how they are being untruthful about their purification of water. Although she believes they are untruthful, she provides little evidence of that. She is being quite vague about her conclusion that water bottles are not the best source of water.
You correctly answered: d. Because water and many plasma solutes filter into Bowman's capsule. In the presence of ADH, what component of the tubule fluid moves out of the collecting duct and into the interstitial space?

For “the cell” of 20% sugar solution in the 1% sugar solution I predict that the weight will stay the same as well just because it is in a less concentrated solution as “the cell”. Conclusion: The results were very surprising, it was not what I expected at all. My prediction of the cell of 1% sugar solution in the 1% sugar solution was correct. The cell weighed the same after the twenty minutes. This cell was placed in a isotonicity enviroment.
Find the next three terms in each geometric sequence. 5. 10, 20, 40, 80, … SOLUTION: The common ratio is 2. Multiply each term by the common ratio to find the next three terms. 80 × 2 = 160 160 × 2 = 320 320 × 2 = 640 The next three terms of the sequence are 160, 320, and 640.
Discussions need to include what the results mean. You can easily do this in 3-4 sentences. Solubility product constant, or Ksp, is a constant used for predicting solubility of different compounds in solution. In the experiment Ksp is determined for the purpose of knowing how much of a solid dissolves in solution at equilibrium. The Ksp for the experiment was found to be an average of 4.29x10-5, which means that 4.29x10-5 parts of a mole of solid are dissolved in the solution.
Taste Test: Splenda vs. Sugar Taste Test: Splenda vs. Sugar Introduction Americans are more health conscience now than they were decades ago which is why they are completely dedicated to finding ways to consistently reducing the caloric and sugar intake in their diets. As a result, many are focusing on the use of artificial sweeteners and sugar substitutes. Because of this health conscience era, the use of Splenda, in particular is used in just about every food, drink, candy etc. Splenda, along with other artificial sugar product, is popular because it does not add any calories, but what makes Splenda stand apart from other sugar substitutes is its claim that it is made from sugar and taste exactly like sugar. Although widely accepted, there are those that prefers the use and taste of nothing but regular sugar because they do not like the tast of the artificial sugars on the market, however, although Splenda’s claim of being made from sugar and taste exactly like sugar, there are those that swear that they could taste the difference between the two.
On the first bottle I learned how to spew Pepsi all over the room. For the other two bottles I found that each one contained about 2.2 grams of carbon dioxide under pressure dissolved in the liquid! That is enough gas to fill up a liter bottle at standard temperature and pressure! This is not all of the carbon dioxide in the soda. There is still carbon dioxide gas dissolved in the liquid at atmospheric pressure.
