A discarded spray paint can contains only a small volume of the propellant gas at a

Katena32 [7]

Answer:

1.24 × 10³ kPa

Explanation:

Step 1: Given data

Initial pressure of the gas (P₁): 34.5 kPa

Initial volume of the can (V₁): 473 mL

Final pressure of the gas (P₂): ?

Final volume of the can (V₂): 13.16 mL

Step 2: Calculate the final pressure of the gas in the can

If we assume that the gas in the can behaves as an ideal gas and that the temperature remains constant, we can calculate the final pressure of the gas using Boyle's law.

P₁ × V₁ = P₂ × V₂

P₂ = P₁ × V₁ / V₂

P₂ = 34.5 kPa × 473 mL / 13.16 mL = 1.24 × 10³ kPa

A student wants to investigate how the beaver is differnt from most other mammals in the wild

timofeeve [1]

Answer:

I believe the options are:

a. How many other mammals eat trees or other plants to survive?

b. How many other mammals live in an environment that includes water?

c. Do most other mammals have body structures adapted to the places where they live?

d. Do most other mammals change the environment to meet their survival needs?

Explanation:

Beavers, the largest rodents in North America, are classed as a keystone species i.e their presence affects other organisms as well as the abiotic factors in an ecosystem. Beavers enhance the habitat quality of a particular region and make it habitable for other organisms.

Beavers build dams that form wetlands that are home to majority of species in North America.
They filter water from silt and increase the quality of water.
They are "ecological indicators" i.e. they can help establish the health status of an ecosystem.

Calculate the molarity of a solution consisting of 25.0 g of KOH in 3.00 L of solution.

melomori [17]

Answer:

0.15M

Explanation:

The equation for molarity is M= n/L. Where "M" is Molarity, "n" is the number of moles of solute, and "L" is the total liters in solution.

You need to calculate the number of moles from the given grams. The molar mass of KOH is (39.098+ 16 +1.008)= 56.106g. To calculate the mols of KOH, $\frac{25.0g}{1}$ × $\frac{1 mol}{56.106g}$ = 0.44558... mol, you see that the grams unit cancel out leaving you with mol as the unit.
