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 ?
