<u>Given:</u>
Pressure = 565 torr
<u>To determine:</u>
Corresponding pressure in atmospheres
<u>Explanation:</u>
Pressure is commonly expressed in units like:
Atmosphere (atm), Torr or mmHg
The SI unit is atm, where
760 torr = 1 atm
Thus, a pressure reading of 565 torr corresponds to:
565 torr * 1 atm/760 torr = 0.743 atm
Water has a chemical formula of H2O. This means that for every 2 moles of hydrogen and 1 mole of oxygen, one mole of water will be formed.
Note that hydrogen gas and oxygen gas are both biatomic molecules.
(1) (182 mol H2) x (1 mol H2O/ 1 mol H2) = 182 mol H2O
(2) (86 mol O2) x (2 mol H2O / 1 mol O2) = 172 mol H2O
We choose the smaller number of the two as the answer to this item. Thus, the answer to this question is 172 mol of H2O can be formed out of the given quantities.
