“I need you to show all work and the questions i gave you are exactly like what i was asked. On my numbers after each element are subscripts.Concentrated sulfuric acid has a density of 1.84g/cm cubed and is 95.0% by weight H2SO4. What is the molality of this acid? What is its molarity?Phenanthrene, Cl4H10, is an aeromatic hydrocarbon. If you dissolve some phenathrene in 50.0g of benzene, the boiling point of the solution is 80.51 degrees celcius. How many grams of the hydrocarbon must have been dissolved?A mixture of ethanol (C2H5OH) and water has a freezing point of -16.0 degrees celcius. a.)what is the molality of the alcohol? b.)what is the weight percent of alcohol in the solution?List the following aqueous solutions in order of increasing melting point a.)0.10m sugar b.)0.1m NaCl c. 0.08m CaCl2 d.)0.04m Na2SO4How many grams of ethylene glycol, HOCH2CH2OH, must be added to 5.50kg of water to lower the freezing point of the water from 0.0 degrees celcius to -10.0 degrees celcius?An aqueous solution contains 0.180g of an unknown, nonionic solute in 50.0g of water. The solution freezes at -0.040 degrees celcius. What is the molar mass of the solute?”
