Answer:

.135 L

Explanation:

P1V1 = P2V2

1*2=.27*V2

(1*2)/.27 = V2

V2 = .27 ÷ 2 = .135

What is density measured in... for example if i had 68 what would be the suffix for that
Airida [17]

It depends.

If the volume is mL and the mass is g, then the "suffix" would be g/mL.

If the volume is cm3 and the mass is g, then the "suffix" would be g/cm3.

6. Look carefully at the following diagram. It does not obey the law of conservation of matter. Explain why it does not follow t
Basile [38]

Answer:

Sort of answer, but it'll lead you in the right direction I hope.

Explanation:

I mean, ofc, the molecules or atoms or whatever the circles are can't be put together that way bc matter says so. It looks like the other diagram is showing water or gas, and if it were turning into the one on the right, then it would usually either settle into water if it was gas or become a single solid object like water. If this is gas, then it doesn't make sense, because gas particles are always separate from each other.

sample of carbon monoxide gas occupies 3.20 L at 125 °C. At what temperature will the gas occupy a volume of 1.54 L if the press
Anna [14]

Answer:

-81.5 degrees C or 191.5 K

Explanation:

We want to use Charles' gas law: V/T = V/T

Our initial volume is 3.20 L, and our initial temperature is 125 degrees C, or 125 + 273 = 398 degrees Kelvin.

Our new Volume is 1.54 L, but we don't know what the temperature is. So, we use the equation:

3.20 L / 398 K = 1.54 L / T ⇒ Solving for T, we get: T = 191.5 K

If we want this in degrees Celsius, we subtract 273: 191.5 - 273 = -81.5 degrees C
