Answer:
The molarity of a solution prepared by dissolving 54.3 g of Calcium nitrate into 355 mL of water is 0.9881M
Molarity of solution is the ratio of the number of moles of the substance to the volume.
n is the number of moles of the compound
Mass of calcium nitrate = 54.3g
Molar mass of calcium nitrate = Ca(NO₃)₂ = 164.088 g/mol
Get the required molarity;
Hence the molarity of a solution prepared by dissolving 54.3 g of Calcium nitrate into 355 mL of water is 0.9881M
Explanation:
:)
2/5 of 25 = 20 then the rest of the way for FG is 3/5 of the way, = 15
A. Density increases
The density of planet earth is the lowest at the surface and increases the further you move to the middle.
The fear is caused by the restriction of blood flow to the reticular system of the brainstem. This affects the amygdala that is connected to the hypothalamus, which are part of the diencephalon. The difficulty in speaking is caused by damage to Borca's area in the frontal lobe. Blindes in the right visual field is caused by damage to the right occipital lobe.
