The following experiment is used to determine the amount of helium gas in a container. the volume of the container is 4.55 l, the height of the mercury gap is 500. mm, the ambient temperature is 20.°c, and the atmospheric pressure is 771 torr. determine the pressure in the container, the number of moles of gas, and the mass of the gas. pressure in the container 1.67 correct: your answer is correct. atm number of moles of gas .316 correct: your answer is correct. mol mass of the gas 1.264 correct: your answer is correct. g

Consider a file currently consisting of 200 blocks. assume that the file control block (and the index block in the case of indexed allocation) is already in memory. calculate how many disk i/o operations are required for contiguous, linked, and indexed (single-level) allocation strategies, for each of the conditions listed below. in the contiguous-allocation case, assume that there is not room to grow at the beginning but there is room to grow at the end. also assume that the block information to be added is stored in memory.
