or are you confused about the part of getting 20/30 from 2/3
*March 2, 2015*

**4th grade math**

2/3 times 10 equals 20/30 and 21 is greater than 20.
*March 2, 2015*

**4th grade math**

21/30 is greater than 20/30 or 2/3 as long as both number have a zero on the end that zero isnt nedded

oops, disregard the last part it didn't line up right. It will just be 58.14/ 18.02 which gives you moles
*November 4, 2010*

**chemistry**

I believe you would get the molar mass of C4H10 and also the molar mass of water (H20). So C4H10 gives us a molar mass of 58.14 grams/mol and water gives us a molar mass of 18.02 grams/mol. You then would set it up 58.14 grams x mol/ 18.02 grams. Grams cancel and leave you ...

Lysosomes are organelles found in all animal cells. Lysosomes have enzymes that break down food so it's easier to digest ( this is more on the intracellular level). So the enzyme is breaking up macromolecules ( proteins, lipids, etc.)

I tried doing it that way already but it just doesn't look correct, because I set up PV=nRT to n=PV/RT. Entering the numbers I would get ((0.0658 atm)(0.2853))/((0.08206 L*atm/K*mol)(315K)) and I would get 0.000726 moles. After that would I just go straight to the number ...
