The conversion factor between the unit in meter and that of kilometer is that, 1 kilometer = 1000m
For the given above,
(288 m³) x (1 km / 1000 m)³ = 2.88 x 10^-7
Thus, 288 m³ is also equal to 2.88 x 10^-7 km³.
Spheres representing Oxygen and Nitrogen are different colors so that it is easier for you to see.
Answer:
Molarity = 0.08 M
Explanation:
Given data:
Mass of copper sulfate = 3.8 g
Volume of water = 250 cm³ (250/1000 = 0.25 L)
Concentration of solution = ?
Solution:
Number of moles of copper sulfate:
Number of moles = mass/molar mass
Number of moles = 3.8 g/ 159.6 g/mol
Number of moles = 0.02 mol
Concentration:
Molarity = Number of moles / volume in L
By putting values,
Molarity = 0.02 mol / 0.25 L
Molarity = 0.08 mol/L
Molarity = 0.08 M
Expected to deal with what? Fires?
Your answer is J, because electrons orbit the nucleus of an atom and have a negative charge
