A research worker isolated an unknown compound from one of his reaction product. This compound was a volatile liquid with a boiling point of 65oC. A 0.134 g sample of the liquid was vaporized and the gas was collected. The temperature of the collecting chamber was kept at 98oC in order that liquefaction would not occur. After all the sample was vaporized, the volume of the gas was measured at 0.0532 l at 98oC and 737 mmHg. Calculate the molecular weight of the compound.​

How many moles of solute are there in 7.0 L of a 0.200 M NaCl(aq)? Report your answer with one decimal place.

Can I get a tutor for this module and how much do you cost

What is the change of reaction when temperature decreases from 100°C to 70°c if the temperature coefficient is 2

What would be the final concentration of a solution containing 20mL of 1.5% NaCl solution diluted to 200mL

Magnesium chloride can be made by reacting excess magnesium carbonate with dilute hydrochloric acid.
The equation for the reaction is
MgCO3 + 2HCl → MgCl2 + H2O + CO2
(a) In an experiment 0.050 mol of MgCO3 reacts with excess HCl.
A yield of 5.5 g of MgCl2.6H2O is obtained.
(i) Calculate the percentage yield of MgCl2.6H2O

Lattice energy of Al2o3 is more than pbO why
