Answer:
212.8 dm^3 or L
Explanation:
1 mole of any sub=6.02×10^23 molecules
X mole of O2=5.7×10^24 molecules
X mole=5.7×10^24/6.02×10^23
=9.5 mole
1 mole of any gas at stp=22.4 dm^3
Therefore, 9.5 mole of O2 will be 22.4×9.5
=212.8 dm^3
Answer:
Water- 9.982 grams
toluene-8.669 grams
chloroform - 14.832 grams
Explanation:
the units of density are listed as g/mL. So for every mL of substance you have, you will have that many grams.
Water- .9982g/mL * 10 mL
As you can see, the units of "mL" cancel each other out, leaving just the gram amount of water.
