Problem- A compound contains 42.9% C, 2.4% H, 16.6% N, and 38.1% O by mass. The addition od 3.16g of this compound to 75 mL of cyclohexane (d= 0.779g/ml) gives a solution with a freezing point of 0.0 degrees Celsius. The normal freezing pt of cyclohexane is 6y.50 degrees Celsius and its freezing pt depression constant of 20.2 degrees Celsius/m. what is the molecular formula of the solute?
Explain the each and every step in detail for help
If 2.00 g of the base form of cocaine are recovered, was the original sample a pure sample or a mixture? If it was a pure sample, was it a compound or an element. If it was a mixture was it heterogeneous or homogeneous

In an electrolytic cell, Cu(s) is produced by the electrolysis of CuSO4(aq). Calculate the maximum mass of Cu(s) that can be deposited by a direct current of 100. amperes passed through 5.00 L of 2.00 M CuSO4(aq) for a period of 1.00 hour.
A sealed container holds 1.00 mole of helium and 2.00 moles of nitrogen at 30.0°C. When the total pressure of the mixture is 666 mm Hg, what is the partial pressure of the nitrogen? Provide an answer correct to 2 significant figures in mmHg.
In the electrolysis of aqueous NaClO3, how many liters of Cl2(g) (at STP) are generated by a current of 60.0 A for a period of 80.5 min? Use R = 0.0821 L-atm/mol-K for the gas constant and use F = 96,500 C/mol for Faraday's constant. Assume that 0..
a buffer solution is prepred by adding 15.00g of sodium acetate (NaC2H3O2) and 12.50g of acetic acid to enough water to make 500mL (three significant figures) of solution.
How is concentration an intensive property? I mean if you add more amount of a substance(mass), the number of moles increase and so the concentration increases.
Problem- How much heat (in kJ) is evolved (under standard conditions) when 83.84 g of copper reacts to form copper(II) oxide
