log 10=1 log 100=2 log 1000=3 and so on.
now,coming to your question,
log 0.130 is same as log 130/1000.
log 130/1000 = log 130 - log 1000
= 2.113 - 3
= -0.8860.
R-COOH dimerises in benzene upto 50% and it ionises upto 10% in water.Detrmine the ratio of Van't hoff factors in dimerisation v/s ionisation?
when NaCl is added to aqueous of glucose
Two liquids A and B on mixing form ideal solution. their vapour pressures in pure state are 200 and 100 mm respectively. what will be the mole frction of B in the vapour phase in equillibrium with an equimolar solution of two?
The answer is 0.33..!!! how to get it??
Two liquids A and B on mixing produce a warm solution. Which type of deviation from Raoult's law does it show?
what product is obtained when alcohols are heated with NaI or KI in 95% phosphoric acid ?
