Milk has a density of 1.04 g/ml. if you have a volume of 510 ml, what is the mass in grams

Density is defined as the ratio of mass and volume. The formula of density is:

    -(1)

Density of milk =   (given)

Volume of milk =      (given)

Substituting the values in formula (1):

Hence, the mass of the milk is .

  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-

the answer is 75.0%.
