An liquid's mass is 79.6 g. A student measures the volume to be 42.5mL. What is the density of the liquid?

The answer is

Explanation:

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

From the question

mass of liquid = 79.6 g

volume = 42.5 mL

The density of the liquid is

We have the final answer as

1.87 g/mL

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-
