The first law here is Charles's law and the new volume will be 285.08 mL

Converting degree celsius to kelvin when solving gas laws problem.

kelvin = degree celsius + 273.15

Kelvin = 19 + 273.15 = 292.15 K

Kelvin = 60 + 273.15 = 333.15 K

Given Data:

V1 (initital volume) = 250 ml

T1 (initial temperature) = 19°c or 292.15 K

V2 (final volume) = unknwon ?

T2 (final temperature) = 60°c  or 333.15 K

Charles' law which states that volume is directly proportional to temperature when the amount and pressure of the gas are constant.

Applying the formula, we get

V2 = V1T2 / T1

   = 250 ml × 333.15 K / 292.15 K    (cancel kelvin unit)

    = 83287.5 ml / 292.15

    = 285.08 ml

The new volume will be 285.08 ml

Given the following masses, calculate the mass of water lost & determine the percent hydration.
lisabon 2012 [21]
<span>You are given the mass of hydrate which is 10.24g and the mass of anhydrate which is 8.74g. Hydrate means that it contains water and anhydrate means the substance has lost water during the process. So you just subtract them, 10.24g – 8.74g = 1.5g of water is lost. Percent hydration is equal to one subtracted to the mass of anhydrate divided by the mass of hydrate multiplied by 100. So we have, [1-(8.74g/10.24g)] *100 = 14.65% or 15%. Your answers are correct.</span>
