A gas measuring 525 mL is collected at 104.66 kPa. What volume does this gas
Olegator [25]

Recall the ideal gas law:

<em>P V</em> = <em>n R T</em>

where

<em>P</em> = pressure

<em>V</em> = volume

<em>n</em> = number of gas molecules

<em>R</em> = ideal gas constant

<em>T</em> = temperature

If both <em>n</em> and <em>T</em> are fixed, then <em>n R T</em> is a constant quantity, so for two pressure-volume pairs (<em>P</em>₁, <em>V</em>₁) and (<em>P</em>₂, <em>V</em>₂), you have

<em>P</em>₁ <em>V</em>₁ = <em>P</em>₂ <em>V</em>₂

(since both are equal to <em>n R T </em>)

Solve for <em>V</em>₂ :

<em>V</em>₂ = <em>P</em>₁ <em>V</em>₁ / <em>P</em>₂ = (104.66 kPa) (525 mL) / (25 kPa) = 2197.86 mL

The radius of the base of a sugar cone is 1.5 inches and the cone is 8 inches tall.
g100num [7]

Answer:

about 18.85 cubic inches of ice cream can fit inside the cone

Step-by-step explanation:

To understand this, you will need to know the formula for a cone's volume which is

πr^2 times h/3

h being the height of the cone

to clarify the equation is pi (3.14) times the radius squared (which means you put it to the power of 2) and you multiply it by the height divided by 3.

Step by step:

π(1.5)^2 times 8/3

put it in a calculator and solve

round according to the problem

hope it helps
