Hello,

I am in university( first year) and I need help in Chemistry's lab.

okay we did a lab on determination of gas constant R.

and I need to report atlest 4 possible sources of systematic errors.

To give brief Intro " material used were Burette appratus which is used to measure the vol. of H2 gas, two samples of metal, HCl, erlenmeyer flask.

In this experiment we had to measure the vol of hydrogen gas when a known metal was reacted with excess HCl, strong acid. nd then we used experimental data to find gas constant R.

I hope i provided enufff info.

Plzz i need ans ASAP.THnxx in advance.
