Halogen acid gas evolution the level of HCL evolved percent by weight .Test result 2mg/g the sample weight 0.65 gram calculat the percent by weight.
To calculate the percent by weight of halogen acid gas evolution (HCl) based on the test result, you will need to use the given values. Here's how you can do it step-by-step:
Step 1: Convert the test result from milligrams per gram (mg/g) to percent by weight.
The given test result is 2 mg/g. To convert this to percent, divide the test result by the sample weight and multiply by 100.
HCl evolved (in grams) = Test result / 1000 (to convert milligrams to grams)
= 2 mg / 1000
= 0.002 grams
Percent by weight = (HCl evolved / Sample weight) * 100
= (0.002 g / 0.65 g) * 100
= 0.3077 * 100
= 30.77%
Therefore, the percent by weight of HCl evolved is approximately 30.77%.
