You weigh three samples of the same metal, and find their masses to be 35.71 g, 39.04 g, and 40.81 g. the corresponding volumes are 3.9 ml, 4.5 ml, and 4.5 ml. what is the density, d, of the metal?

The density of metal is 8.97 g/mL

Explanation:

Density of a substance is defined as the ratio of its mass and volume. The chemical equation representing density of a substance is:  

        .......(1)

Mass of sample 1 = 35.71 g

Volume of sample 1 = 3.9 mL

Putting values in equation 1, we get:

Density of sample 1 = 9.16 g/mL

Mass of sample 2 = 39.04 g

Volume of sample 2 = 4.5 mL

Putting values in equation 1, we get:

Density of sample 2 = 8.68 g/mL

Mass of sample 3 = 40.81 g

Volume of sample 3 = 4.5 mL

Putting values in equation 1, we get:

Density of sample 3 = 9.07 g/mL

Putting values in above equation, we get:

Hence, the density of metal is 8.97 g/mL

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.

catya your not at all which answer i've seen you do this on another question!
