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.

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
