بناات هذي السؤالييين حااولت احلهم كثير بس الناتج يطلع غلط احد يفهمني
A mixture of three gases has a total pressure of 1700.0 mmHg at a certain temperature.
The mixture is analyzed and is found to contain 55 g CO2, 84 g CO, and 62 g Ar.
What is the partial pressure of CO2 ?





Calculate the volume of PH3 at 20°C and 871.0 mmHg that can be prepared by additing a water to 1.48 g of Ca3P2.
Ca3P2(s)+6H2O(l)=3Ca(OH)2(s))+2PH3(g)
