Three test tubes contain white crystalline organic solids a, b, and c, each of which melts at 149-150 degrees c. a 50-50 mixture of a and b melts at 130-139 degrees c. a 50-50 mixture of a and c melts at 149-150 degrees c. in what range would a 50-50 mixture of b and c probably melt? what can you say about the identities of a, b, and c?

Someone offer some answers to this, i will give 98 coins and mark as brainliest! i will put the rest of the lab down in the comments, solutions pre-lab questions: in this lab, you will make fruit drinks with powdered drink mix. complete the pre-lab questions to get the values you need for your drink solutions. calculate the molar mass of powered fruit drink mix, made from sucrose (c12h22o11).using stoichiometry, determine the mass of powdered drink mix needed to make a 1.0 m solution of 100 ml. (hint: use molarity = to find the moles of drink mix, then convert moles to grams using a mole conversion.)what mass of powdered drink mix is needed to make a 0.5 m solution of 100 ml?
