i have chemistry homework, there are 6 questions i need help with them, i want the whole steps in the paper. 11. A certain brand of gasoline has a density of 0.67 g/mL. If a car has a gas tank capacity of 16 gallons, how many pounds of gasoline are in a full tank? 12. Which of the following is the highest temperature? A. 28EF B. 249K C. 6.1EC 60 13. The density of a sample was determined by water displacement. The initial water level was 23.4 mL. After adding the 7.59-g sample, the level increased to 27.7 mL. Calculate the sample density to the proper number of significant figures. 14. The density of chloroform is 1.48 g/mL. What is the volume in liters of 6.5 kg of chloroform? 15. A certain container weighs an unknown number of grams, which is 8 more grams than its lid. Write a mathematical expression for the combined mass of the container and lid. 16. If you are advised by your doctor to take 2 teaspoons of a medication 3 times a day for 10 days, what is the minimum volume of medication (in mL) you will need?
