What volume of H2 gas (in L), at 748 mmHg and 86 °C, is required to synthesize 25.8 g CH3OH ? How many liters of CO gas, measured under the same conditions, are required?

Thus volume of hydrogen is 48.7 L and volume of CO is 24.4 L

Explanation:

The balanced chemical reaction is :

To calculate the moles :

According to stoichiometry :

1 mole of require = 2 moles of

Thus 0.81 moles of will require=  of

To find Volume of hydrogen :

According to ideal gas equation :

P= pressure of gas = 748 mm Hg = 0.98 atm   (760mmHg=1atm)

R = Gas constant =

T = temperature of the gas =

V = volume of gas = ?

n = number of moles = 1.62

According to stoichiometry :

2 moles of require = 1 moles of

Thus 1.62 moles of will require= of

To find Volume of CO:

Thus volume of hydrogen is 48.7 L and volume of CO is 24.4 L
