Answer:
Formula Weight of gas sample = 20.1 g/mole => Neon (Ne)
Explanation:
Use Ideal Gas Law formula to determine formula weight and compare to formula weights of answer choices.
PV = nRT = (mass/fwt)RT => fwt = (mass/Volume)RT = Density x R x T
Density = 0.900 grams/L
R = 0.08206 L·atm/mole·K
T = 0.00°C = 273Kfwt = (0.900g/L)(0.08206L·atm/mole·K )(273K)
= 20.1 g/mol => Neon (Ne)
Answer:
A
Explanation:
The only factor that would not decrease the carrying capacity of the fur seal's environment is the population of predators.
<em>The carrying capacity is defined as the maximum number of individuals of a species an environment can sustain based on the resources available. Hence, only a fluctuation in the resources available in the environment of the fur seal can affect the carrying capacity. </em>
<u>Pollution </u>and <u>destruction of the habitat of the fur seal</u> would limit the resources available to the animals and as such, limit the carrying capacity. A <u>fluctuation in the population of prey available</u> for the population of fur seals would also affect the carrying capacity.
The only factor that has no bearing on the carrying capacity of the fur seal's environment is the population of predators. Predators have the capacity to reduce the population of fur seals but not affect the carrying capacity for fur seals.
The correct option is, therefore, A.
Answer : The volume of solution will be 2.96 liters.
Explanation :
Molarity : It is defined as the number of moles of solute present in one liter of volume of solution.
Formula used :
In this question, the solute is NaF.
Now put all the given values in this formula, we get:
Therefore, the volume of solution will be 2.96 liters.
