Answer:

It is C

Explanation:

A) does not make sense because we obviously see that it has 2 moles of AB (right side of equation) for every 3 moles of A (left side of equation). We do not have data to prove B) is correct. It would require data actually. We also do not have data to prove that D is true either. But, we do know based on the equation that "for every two AB produced, teh reaction requires three A."

1.95 or 2 is the molarity of a 45.3g sample of KNO3 (101g) dissolved in enough water to make a 0.225L solution.

The correct answer is option b

Explanation:

Data given:

mass of KN $O_{3}$ = 45.3 grams

volume = 0.225 litre

molarity =?

atomic mass of KNO3 = 101 grams/mole

molarity is calculated by using the formula:

molarity = $\frac{number of moles}{volume of the solution}$

first the number of moles present in the given mass is calculated as:

number of moles = $\frac{mass}{atomic mass of 1 mole}$

number of moles = $\frac{45.3}{101}$

0.44 moles of KNO3

Putting the values in the equation of molarity:

molarity = $\frac{0.44}{0.225}$

molarity = 1.95

It can be taken as 2.

The molarity of the potassium nitrate solution is 2.

<span>This example represents the challenge of survival of the fittest. In this situation, the trees have a distinct advantage due to their above average height. This puts them in the best position to gain the resources that they need to survive, most notably, the sun. The smaller plants, however, do not have this advantage, and lose out to the trees.</span>

Calculate the volume which 1.00 mole of a gas occupies at 1 atm and 298K?

elena-14-01-66 [18.8K]

Answer:

25.45 Liters

Explanation:

Using Ideal Gas Law PV = nRT => V = nRT/P

V = (1mole)(0.08206Latm/molK)(298K)/(1atm) = 25.45 Liters
