What is the total pressure on the gas after the 760 mm hg has been added?
first phase atmospheric pressure= 760 torr gas volume= 60 ml (760 mm hg added to 2nd phase) second phase atmospheric pressure= 760 torr gas volume= 30 ml **image looks like a j. in the 2nd phase, there is 760 mm that is half of the j** if that makes any sense.
i am confused on how you solve the problem considering the torr and ml and mm and mmhg

1520 torr = 1520mmHg = 2 atm.

Explanation:

Please note that it is just basic conversion.

1 torr = 1mmHg

1 atm = 760mmHg = 760 torr

As per the question,

FIRST PHASE:

760 torr pressure is applied which gave = 60mL volume to gas.

SECOND PHASE:

760mmHg pressure is applied which gave = 30mL volume to gas

Since we know that 1mmHg = 1 torr.

Therefore, total gas pressure = 760 + 760 = 1520 torr OR 1520mmHg

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
