1.A sample has a mass of 15 g and a volume of 3 mL. Calculate the density.

Explanation:

The density of a substance can be found by using the formula

From the question

mass = 15 g

volume = 3 mL

We have

We have the final answer as

Hope this helps you.

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.
