Answer:
Hello. We have a question which is based on the ideal gas law which is in chemistry, ideal gas law is PV equal to an R. P. Where P is the pressure. And in our question, pressure is being given as, what is it? 1.4 atmosphere pressure, 1.4 atmospheric pressure volume. These volume in liters. What is the volume is given? 15.1 liters. 15.1 leaders. And is the number of moles of the gas which we have to find out and are is the universal gas constant, which is 0.8 to one later atmospheric constipation by mole mole kelvin. This is later atmosphere per unit mole per kelvin. Okay. And t. Is the temperature in Calvin's which has been given as 430 for 30 kelvin. So we have to find the value of N from this universe. This ideal gas. So ideal gas constant. I didn't get the question. I'm sorry. Yes. And equal to B V by RT. So let us I'm just plugging the values and will be equal to PV priority. So pressure is being given as 1.4 atmospheric pressure volume age. 15 points on leaders and art is zero point 08210108 to one 08 to one later atmosphere. But Calvin and per mole and temperature is 400 30 kelvin. Okay. So this atmosphere and later will get cancelled out. The scallion Calvin will get cancelled out. So I was of K if we calculate the value of N value of N will be equal to zero point. We have two is calculated. Okay. Does he look fine? 5988 one 59 81 mall. So this is the number of, this is the number of moles of hydrogen. So number of moles approximately will be equal to zero point 60 Okay, so this is the amount of how did I guess we need? Thank you.
