Re: Chemistry

Then choose that answer because 3.04747 gms is 3.05 gms when you round to 3 significant digits. I worked with more precision then your question provides.

Re: Chemistry

Back then the emphasis was on technique, the handling of glassware and equipment. Chemistry was hands on for everything. When I saw any math in it I just shut down.
