Explanation:
From your information above, assume 1 month is 28 days
1 days=24hours ; 28 days=672 hours (just multiply 1 days with 28)
1 hour=60minutes ; 672 hours=40,320 minutes
.. 1 month=40,320 minutes
Answer:
there are 4 hydrogen so
A.the mass of Hydrogen in the reactant side of the equation above is 1×4=4 amu.
B.the mass of Hydrogen on the product side of the equation above =1×4=4 amu.
<u>Note</u><u>:</u><u> </u><u>mass</u><u> </u><u>of</u><u> </u><u>reactant</u><u> </u><u>=</u><u>mass</u><u> </u><u>of</u><u> </u><u>product</u><u>.</u>
i would have to say boiling because all that does is make the molecules do that fancy word for moving to the surface when they heat.
Answer:
1.126 M
Explanation:
From the question given, we obtained the following:
Mass of LiBr = 98g
Volume = 1 L
Molarity of LiBr =?
Next, we'll determine the number of mole of LiBr. This is illustrated below:
Molar Mass of LiBr = 7 + 80 = 87g/mol
Mass of LiBr = 98g
Number of mole = Mass/Molar Mass
Number of mole of LiBr = 98/87
Number of mole of LiBr = 1.126 mole
Now, we can calculate the molarity of LiBr. This is illustrated below:
Molarity is defined as mole per unit litre of the solution. Mathematically, it is represented as:
Molarity = mole /Volume
Mole of LiBr = 1.126 mole
Volume = 1 L
Molarity of LiBr =?
Molarity of LiBr = 1.126 mole /1 L
Molarity of LiBr = 1.126 M
Maybe it would make cows stop getting killed if everyone stopped eating fast food for burgers idk maybe Xd
