A doctor orders a blood sample from a child to test for traces of lead in the blood. Which of the following concentration units would best meet this need?
O grams per liter O molality
O percentage by mass
O parts per million

How many grams of co(g) are there in 74.5 ml of the gas at 0.933 atm and 30o 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?
