Hello, I need help on these questions if you can answer all of them? I gave you a data table and questions you can go ahead with. Some clarification is that for question 3 it's asking to find the the density of NaCI. And I also used 12 grams of sodium chloride. For each calculation, you will be required to show detailed work steps. Make sure the number of eachquestion is clear according to what was in the introductions and procedure document. Meaning, makesure that your use of the template doesn't mess up the numbering!Post lab questions1) Find the percent by mass of NaCl in solutionUse Equation editor here to show all your work!

Precipitation from a supersaturated sodium acetate solution. The solution on the left was formed by dissolving 141 g of the salt in 100 mL of water at 100 ∘C and the slowly cooling it to 20∘C.Because the solubility of sodium acetate in water at 20 ∘C is 46 gg per 100 mL of water, the solution is supersaturated. Addition of a sodium acetate crystal causes the excess solute to crystallize from solution. How many grams of sodium acetate are in solution in the third beaker? Express your answer as an integer.
The calorie (4.184 J) was originally defined as the quantity of energy required to raise the temperature of 1.00 g of liquid water 1.00°C. The British thermal unit (Btu) is defined as the quantity of energy required to raise the temperature of 1.00 lb of liquid water 1.00°F.(a) How many joules are in 1.00 Btu (1 lb 453.6 g; a changeof 1.0°C= 1.8°F)?(b) The therm is a unit of energy consumption and is defined as 100,000 Btu. How many joules are in 1.00 therm?(c) How many moles of methane must be burned to give1.00 therm of energy? (Assume water forms as a gas.)(d) If natural gas costs $0.66 per therm, what is the cost per moleof methane? (Assume natural gas is pure methane.)(e) How much would it cost to warm 318 gal of water in a hottub from 15.0°C to 42.0°C (1 gal 3.78 L)?
The maximum dose over 24 hours for OTC (over the counter use) of acetaminophen (medication in Tyleonol) is 4,000 mg. Many OTC and prescription medications contain acetaminophen along with other ingredients. Acetaminophen can be found in many cold medicines and in prescription painkillers such as Norco, which also contains the addictive opiod hydrocodone. Keeping track of sources and amount of acetaminophen is very important for your health. Abuse of Norco due to the opiod can also lead to toxic/lethal doses of acetaminophen. There are now strict regulations on the number of tablets of Norco that can be prescribed (7 day maximum per prescription, not refillable without another prescription). A tablet of Norco contains 325 mg of acetaminophen. Thirty tablets are in a week-long prescription post major-surgery to aid in recovery. How many grams of acetaminophen are in the 30 tablets?
