Calculate the mass of 12 ml of a substance whose density is 1.1 g/ml. express your answer in grams using the correct number of significant figures. do not enter your answer using scientific notation.

Explanation:

It is known that density is the amount of mass which is present in a liter of substance.

Mathematically,         Density =

It is given that volume is 12 mL and density is 1.1 g/ml. Hence, the density will be calculated as follows.

                      Density =

                         1.1 g/ml =

                        mass = 13.2 g

Thus, we can conclude that mass of the given substance is 13.2 g.

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.
