6. If an object is an irregularly shaped solid and it is dropped into a graduated cylinder andit displaces 25 mL of water and has a mass of 50 grams what is the density of this
irregular shaped object?

Answers

Answer 1
Answer:

Answer:

d = 2 g/mL

Explanation:

Given that,

Water displaced by an object in a graduated cylinder, V = 25 mL

Mass of the object, m = 50 g

We need to find the density of this irregular shaped object. It is given by mass per unit volume. So,

d=(m)/(V)\n\nd=(50\ g)/(25\ mL)\n\nd=2\ g/mL

So, the density of the object is 2 g/mL.

Benedict’s solution is an alkaline copper sulfate solution which is used to detect the presence of aldehyde groups. In the presence of Benedict’s solution, the aldehyde group is oxidized and the aqueous blue Cu2+ ion is reduced to a red Cu2O precipitate. Sugars such as glucose, which produce the red precipitate when Benedict’s solution is added, are called reducing sugars because they can reduce Cu2+ to Cu+. Which of the following carbohydrates would give a positive reaction with Benedict’s reagent? a. galactose; b. sorbitol (see below); c. β-ethylglucoside; d. gluconate .

Suppose experiment was performed with the monosaccharide fructose instead of glucose. A beaker was filled with 30 ml of DNP + 15 mM fructose, and an everted intestinal sac was filled with Mammalian Ringers+ 10 mM fructose. Predict the final concentration of fructose inside the sac after 1 hr incubation at 37°C.

Answers

Answer:

greater than 10 mM.

Explanation:

This question deals with the transport of monosaccharide into the everted sacs of the intestine. And in order to be able to solve this question efficiently one must have prerequisite idea on the transport protein for the Sodium ion process of absorption. Also, one must know the structure of the epithelial.

What happens during the experiment is that there will be an absorption of the fructose, the Chloride ion and the Sodium ion and this absorption will lead to the production of osmotic gradient. Therefore,as the osmotic is produced, the fructose will be transported into the sac through diffusion and thus increasing the concentration of fructose.
