Answer:
The molarity of the solution remains unchanged.
Explanation:
Consider the formula for the molarity
of a solution:
,
where
is the number of moles of solute in this solution, and
is the volume of the solution.
For this salt solution,
, and
.
Initial molarity:
.
Final molarity:
.
In other words, the molarity of the solution remains unchanged.
Answer:
1 = 252g, 2 = 2mL, 3 = 1.5mL, 4 = 3g, 5 = 225g, 6 = 0.92g/mL, 7 = 0.75g/mL, 8 = 0.71g/mL, 9 = 1.9mL, 10= 1.11mL, 11 = 76.9g
Explanation:
This problem is testing how well you can move around the equation D = m/v where D = Density (g/mL), m= mass of sample (g), v = volume of sample (mL).
Answer:
Molarity tell us about the concentration of moles of solute in a solution.
Explanation:
Chemical substances are measured in terms of mole. Mole is defined as the amount of substance which contains 6.022×10²³ particles, ions or atoms. In System of international, amount of substance is measured in moles. So molarity tells us more information about amount of solute in a solution as compared to percent solution.
Answer:
Solar power
Or in some cases, from heat from the sun. ... Solar energy is a renewable free source of energy that is sustainable and totally inexhaustible, unlike fossil fuels that are finite. It is also a non-polluting source of energy and it does not emit any greenhouse gases when producing electricity.
