Individual samples of O2, N2, and He are present in a 1.25 L, 2.40L, and 6.10L vessel respectively. Each exerts a pressure of 1.50 atm. If all three gases are forced into the same 1.00 L container with no change in temperature, what will be the resulting pressure? What is the partial pressure of O2, N2, and He in the mixture?

Is cm the same as cm3?

A method of analysis yields masses of gold that are low by 0.4 mg. This method is used for analysis of ores that assay about 3.1% gold. What minimum sample mass should be taken if the relative error resulting from a 0.4-mg loss is not to exceed a. -0.1%? Mass = b. -0.4%? Mass = 6. C. -0.8%? Mass = %3D d. -1.1%? Mass =
