Dalton’s Law �In a mixture of gases, the total pressure in the sum of the partial pressures �Ptotal = P 1 + P 2 + P 3 …+ Pn �Example: In a container you have gas A with a pressure of 100 k. Pa, gas B with a pressure of 250 k. Pa, and gas C with a pressure of 200 k. Pa. What is the total pressure? � 100 k. Pa + 250 k. Pa + 200 k. Pa = 550 k. Pa
