Lab 8 Ouiz Name:
1. A student poured 1.2 mL of a volatile liquid into a 250 mL flask. The student then sealed the
flask (except for a very small hole) and lowered the flask into boiling water (100.0° C), allowin;
the liquid to vaporize and warm for 10 minutes. He then cooled the flask to condense the vapor
and he weighed it. Lastly, he washed the flask out, filled it with water and weighed it again.
Density of water is 1.00 g/mL
Barometric pressure = 751.3 mmHg
Mass of empty flask = 79.28 g
Flask with condensed vapor = 80.32 g
Flask with water = 347.84 g
a) Determine the pressure of the unknown vapor in atm.

Look at the bean data from days 4–6. use these data to explain how natural selection changed the number of dark red walking beans over time. writing part

Astudent reacts 13 moles of iron with 21 moles of oxygen according to the following equation:

Someone offer some answers to this, i will give 98 coins and mark as brainliest! i will put the rest of the lab down in the comments,solutions pre-lab questions: in this lab, you will make fruit drinks with powdered drink mix. complete the pre-lab questions to get the values you need for your drink solutions. calculate the molar mass of powered fruit drink mix, made from sucrose (c12h22o11).using stoichiometry, determine the mass of powdered drink mix needed to make a 1.0 m solution of 100 ml. (hint: use molarity = to find the moles of drink mix, then convert moles to grams using a mole conversion.)what mass of powdered drink mix is needed to make a 0.5 m solution of 100 ml?
