Achemist prepares a solution by dissolving 0.3 mole of cacl2 in enough water to make 1000 ml of solution. what is the molar concentration of chloride ions?

dissolves in water to give and  ions according to the following reaction:

 -------->    + 2

So, according to the above reaction, 1 mole of produce 2 moles of  ion,

So, 0.3 mole will give = 0.3 x 2 = 0.6 moles of   ion

So, Molar concentration = 

Note: 1L = 1000mL 

It dont even matter because at the end of thre day we gone life like it ius s

The density of water is 1 g/cm cubed and in order for the pebble to sink its density has to be greater than the density of water and in order for the twig to float its density has to be less than the density of water
