How many molecules are in 9.95 moles of Co2?

Chemistry
1 answer:
AlekseyPX3 years ago
5 0

by applying the equation :

n = N/L

where

n = mol

N = number of molecules

L = avagardro constant

therefore :

N = n × L

= 9.95mol × 6.022 ×10²³ mol-¹

= 59.9189

(this has no units)

Calculate the molarity of a sugar solution if 4 liters of the solution contains 12 moles of sugar.
castortr0y [4]

Answer:

3M

Explanation:

Molarity is one of the measures of the molar concentration of a solution, which can be calculated by using the formula below:

Molarity = number of moles ÷ volume

From the information given in this question, 4 liters of a solution contains 12 moles of sugar. This means that n = 12mol and V = 4L

Molarity = n/V

Molarity = 12/4

Molarity = 3

Hence, the molarity of the sugar solution is 3mol/L or 3M

Like Father Like Mother What is the best summary of this oassage
vovangra [49]

Answer:

hope this helps <3

Explanation:

Landon glances across the dinner table and thinks to himself that his fathers curly hair looks just like his own. He wishes his hair were straight like his mothers because he thinks he looks better with straight hair. Landon works hard to keep it straighter by combing and using hair gel, but it usually curls right back up. He has his mothers nose, but not her hair, unlike his sister Emily, who is also the result of the combination of the DNA from both of his parents and has straight hair like their mothers. Most eukaryotic organisms, like Landon, are formed through the process of sexual reproduction. Landon realizes that he and Emily are evidence that sexual reproduction, the combination of their two parents, creates diverse offspring.

Landons dinner plate is filled with one of his favorite foods-mashed potatoes made from potatoes fresh from his grandmothers garden. He remembers helping her get ready to plant the potatoes in early spring. They cut each potato into several pieces and planted the pieces in a nice straight row in the garden. When these eukaryotic plants came up, he noticed that each plant looked like all the others. These identical offspring with uniform traits are the result of asexual reproduction. Landons grandmother grew potatoes by cutting the whole potato into smaller pieces, which is a type of asexual reproduction called vegetative propagation.

After dinner, Landon wanted to go watch television, but his mother insisted that he put the leftover food in the refrigerator. Perhaps she knew that the cool temperature inside the refrigerator would stop the growth of bacteria, which are prokaryotic and can reproduce asexually in as little as 20 minutes. This rapid asexual reproduction, called binary fission, would produce thousands and thousands of identical bacterial cells that could cause Landons tasty leftover food to spoil before the end of his favorite show.

Landon finishes up the dishes and puts away the leftovers. As he sets the last dinner glass back into the cupboard, he catches a glimpse of his curly hair in his reflection. He thinks to himself that his mothers nose and his fathers hair are actually a good combination that looks pretty good on him
