1. how many millimeters of mercury is 2.64 atmospheres equivalent to? 2.01 x 103 mm hg 3.47 x 10−3 mm hg 2.88 x 102 mm hg 2.64 mm hg 2. if the moles and temperature of a gas are held constant, the pressure of a gas doubles when: volume is halved volume is quadrupled volume is doubled volume is also held constant

2.01 x 103 mm Hg

Explanation:

To convert from atmospheres to millimeters of mercury, it is necessary to know the equivalence between the two units (1 atm = 760.0 mm Hg). The atmosphere units should be arranged to cancel out in order to obtain units in millimeters of mercury.

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.
