this is all the information given and i am having hard time understanding

1. Specifications for lactated Ringer's solution, which is used for intravenous (IV) injections, are as follows for each 100mL of solution: 300mg16mg5.5mg380mg245mgNa+K+Ca2+Cllactate,C3H5O3 a) Which of these ions is the most likely to predominate in the solution? Can we tell just from the masses? 16mgmg1mol=mol300mg b) The solution is made by adding measured amounts of four salts ( NaCl, KCl,CaCl2, and NaC3H5O3 ) into a 100mL solution. What happens to each of the salts when they are dissolved into 25mL of water? Draw a particle picture of each separately, then draw a picture with them all combined. What do you notice about the amount of each ion? c) What is the source of all the lactate in the solution? How would we make sure you have the correct amount of lactate? d), What is the source of all the sodium in the solution? How would you make sure you have the correct amount of sodium
