Floatin' chemistry
WebAffected track. WebPresumably yes, considering the densities of Na (0.968 g/mL) and THF (0.8892 g/mL) sodium shouldn't float on THF. Cutting up the Na is the right way to do it, that the Na should melt is strange though, the m.p. of sodium is above the b.p. of THF... Maybe it stuck to the glass, that might explain why it would melt. Gloominati • 11 yr. ago

WebDensity is a measure of how heavy something is compared to its size. If an object is more dense than water it will sink when placed in water, and if it is less dense than water it will float. Density is a characteristic property of a substance and doesn’t depend on the amount of substance. Note: We are purposely using the terms “size” and ...
