Since molarity is defined as moles per liter, the product of the molarity and volume will remain constant as mole solvent is added. So let's set up an equality to express this
m0*v0 = m1*v1
where
m0, v0 = molarity and volume of original solution
m1, m1 = molarity and volume of final solution.
Solve for v0, then substitute the known values and calculate:
m0*v0 = m1*v1
v0 = (1.75 M * 500 ml)/8.61 M
v0 = (1.75 M * 500 ml)/8.61 M
V0 = 101.6260163
Rounding to 3 significant figures gives 102 ml.
So the original volume of the 8.61 M H2SO4 solution was 102 ml or 1.02x10^2 ml.</span>
Answer:
0.0984mol of F2
Explanation:
The equation for the reaction is given below:
Kr + F2 → KrF2
Let us convert 12g of KrF2 to mole. This is illustrated below
Molar Mass of KrF2 = 84 + (2x19) = 84 + 38 = 122g/mol
Mass of KrF2 = 12g
Number of mole = Mass /Molar Mass
Number of mole of KrF2 = 12/122 = 0.0984mol
From the equation,
1mole of F2 produced 1mole of KrF2.
Therefore 0.0984mol of F2 will produce 0.0984mol of KrF2

whats the question??? I am familiar with brainpop but if u tell me the question ill give u the asnwer
Explanation:
You can cross multiply, it will be easy
Answer:
Plasma.
Explanation:
In science, matter can be defined as anything that has mass and occupies space. Any physical object that is found on earth is typically composed of matter. Matter are known to be made up of atoms and as a result has the property of existing in states. The three (3) classical states of matter are;
I. Solid.
II. Liquid.
III. Gas
Plasma can be defined as a state of matter in which the electrons temporarily separate from the protons and as a result, it is generally referred to as the fourth (4th) state of matter due to its superheated nature.
