Answer:
option c
Explanation:
E = hf
E= energy
h = Planck constant
f = frequency
E = 6.6 X 10^-34 X 4 X 10^14
E = 2.64 X 10^-19J
Explanation:
Since, it is given that density is 1.16 grams per milliliter and molar mass of copper sulfate pentahydrate is 249.68 g/mol.
Now, as we known that density is the amount of mass present in a unit volume.
Mathematically, Density =
Hence, calculate the volume as follws.
Density =
1.16 g/mL =
volume = 215.24 mL
As, 215.24 mL can dissolve in 249.68 g/mol of complex. So, in 100 mL volume amount dissolved will be calculated as follows.
= 116 grams
Thus, we can conclude that 116 grams of copper sulfate pentahydrate that will dissolve in 100 g of water at 0.
Answer:
60.01 kJ energy to melt 180g of ice, <em><u>assuming my figure for heat of fusion.</u></em>
<em><u>Explanation:</u></em>
Please check the wording of the question. "6,01 kmoland the molar - mass of ice is 18.02 g/mol" is hard to interpret.
<em><u>I'll assume the heat of fusion of ice is 6.01 kJ/mole</u></em>?
180 grams of solid water (ice) is 180g/(18.02 g/mole) or 9.999 moles, rounded to 3 sig figs to 10 moles.
(10 moles H2O)*(6.01 kJ/mole) = 60.01 kJ energy to melt 180g of ice.
Answer:
A solvent is a substance that dissolves a solute, resulting in a solution. A solvent is usually a liquid but can also be a solid, a gas, or a supercritical fluid.
