A 2.95 g sample containing a mixture of potassium chloride and potassium iodide was dissolved in a 250.0 mL volumetric flask. 31.50 mL of 0.1000 M AgNO3 was used to titrate a 25.00 mL sample. Calculate the percentage of KCI and KI in the sample for analysis. M(KCI)= 74,50g / mol, M(KI)=166.0 g/mol

Answer it was we, the the whole people, who formed the union. and we formed it, not to give the blessings of liberty, but to secure them: not to the half of ourselves and the half of our posterity, but to the whole people- women as well as men.

We first assume that this gas is an ideal gas where it follows the ideal gas equation. the said equation is expressed as: pv = nrt. from this equation, we can predict the changes in the pressure, volume and temperature. if the volume and the temperature of this gas is doubled, then the pressure still stays the same.
