Body fat has a density of 0.909 g/mL, you are given a 72.8 mL sample of fat. What is the mass of the fat in g?
1: A hydrocarbon contains 7.7% by mass of carbon. The relative mass of the compound is 78. Derive the empirical formula of the compound, it's molecular formula, name the hydrogcarbons and write the structural formula [H=1,C=12]
2: A is a dilute tetraoxpsulphate VI acid, B contains 8g/dm³ of sodium hydroxide of solution. 25cm³ of B requires 20cm³ of A for complete neutralization. Calculate the concentration of B and A in mol/dm³, and, the number of hydrogen ions in 1.0dm³od solution A.
Hello, I have a question, what is the maximum time that 20 sprays of alcoholic perfume (I don't mean normal alcohol, i mean alcohol with adding the strongest fixatives to it to slower the rate of the alcohol evaporation) will evaporate completely ( i mean by completely evaporated like the alcohol taste, color, and odor, is completely gone, also if you poured water on the cloth or head hair or armpit it wouldn’t appear) from your cloth (cotton, fabric, nylon) or head hair or arm pit after spraying it 20 times in -30 degrees Celsius and in 10 degrees celsius weather, thanks.
