500.0 mL of a gas is collected at 745 K. What will the volume be at standard temperature?

183.22mL

Explanation:

Using Charles law equation, which is as follows:

V1/T1 = V2/T2

Where;

V1 = initial volume (mL)

T1 = initial temperature (K)

V2 = final volume (mL)

T2 = final temperature (K)

Note that standard temperature of a gas is 273K.

Hence, based on the provided information, V1 = 500.0mL, T1 = 745K, V2 = ?, T2 = 273K

Using the formula; V1/T1 = V2/T2

500/745 = V2/273

Cross multiply

V2 × 745 = 500 × 273

745V2 = 136500

V2 = 136500/745

V2 = 183.22

At standard temperature (273K), the new volume will be 183.22mL.

Explanation:

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.
