A student measures a pressure increase of 0.25 atm while collecting the H2 gas products from the reaction of Mg with HCl. The theoretical pressure change is 0.29 atm. What is the % yield

Thus the % yield is 86.2%

Explanation:

Percentage yield is the ratio of actual change to the theoretical change in terms of percentage.

The given reaction is :

To calculate the percent yield :

Given : Actual pressure increase = 0.25 atm

Theoretical pressure change = 0.29 atm.

Thus the % yield is 86.2%

fe 55.85 g/mol and h2o 18.02 g/mol.

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
