Hello students, let's look at the equation.
00:02
So here some values are given.
00:06
Value of pressure is equal to 743 mm hg and the value of temperature is equal to 25 degrees celsius and the molar mass of krypton, this is equal to the 83 .798 gram per mole.
00:37
And here required value is density of the krypton solution.
00:41
So first of all convert pressure to atm.
00:46
So pressure is 743 mm hg, so it is multiplied by 1 atm is divided by 760 mm hg, then it is equal to the 0 .977 atm.
01:03
And the temperature is equal to, convert degree celsius into kelvin, and then it is equal to 298 .15 kelvin.
01:16
And calculate the density of the krypton gas using the ideal gas law, that is density is equal to pm is divided by the rt.
01:29
Here density is in gram per liter and p is for pressure of the gas and atm, m is the molar mass of the gas in gram per mole and r is the ideal gas constant and its value is 0 .0821 liter atm per kelvin into mole and t is the temperature of the gas in kelvin.
01:49
So let's put the values...
