Explanation:
Mol is the amount of molecules in something. Mol are similar to donuts, if you have a dozen of something you have 12 of them. If you have a mol of Hydrogen gas you 6.02•10^23 molecules of Hydrogen gas. If you are taking a chemistry class you will probably receive questions involving converting grams to mol and vice versa.
Converting Grams to Mol:
grams of x•(1/molecular mass of x)
note: you can find molecular mass of x by looking at the masses of the elements you need to add up in the periodic table
Converting Mol to Grams:
mol of x•(molecular mass of x)
Answer:
There are 6.024 grams of sodium hydroxide in the solution.
Explanation:
Moles of sodium hydroxide = n
Volume of sodium hydroxide solution = 251.0 mL = 0.251 L
Molarity of the sodium hydroxide = 0.600 M
Mass of 0.1506 moles of NaOH :
There are 6.024 grams of sodium hydroxide in the solution.
C- more than one light year or B-exactly one light year
Answer:
1. The organism becomes ill or may die.
2. Pathogens.
Explanation:
(1) When an organism fails to maintain homeostasis, the organism typically becomes ill, and they will die if homeostasis cannot be re-achieved.
(2) A pathogen is a virus that can cause diseases.
7 valence electrons. Hopefully that's right
