A 30.0 mL solution of 2.0 M hydrochloric acid at 22.0°C was mixed with a 30.0 mL solution of 2.0 M sodium hydroxide at 22.0°C in a styrofoam cup calorimeter (Kcup = 45 J/°C). The final temperature of the mixed solutions was 28.4°C. Calculate the heat of reaction. Assume that the specific heat capacity of the solution is the same as water (4.184 J/g°C).

Determine the empirical formula of a compound containing 40.6 grams of carbon, 5.1 grams of hydrogen, and 54.2 grams of oxygen. in an experiment, the molar mass of the compound was determined to be 118.084 g/mol. what is the molecular formula of the compound? for both questions, show your work or explain how you determined the formulas by giving specific values used in calculations.

What is the mass of 8 moles of sodium atoms

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?
