2) Calculate the density of a rod of metal (in g/cm²) with a mass of 194.41g, a diameter of 2.40 cm and a height of 7.45 cm. Volume cylinder = 1 h/Remember the radius is half the length
of the diameter.
Volume =
Density =
3) Calculate the percent error for your density in question (2), if the accepted density of this
metal is 9.23 g/cm
Percent error = | accepted density - experimental density | x 100
accepted density

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
