6. Calculate what volume of a sulfuric acid solution (specific gravity = 1.07; and containing 10.0 % H2SO4 by mass) contains 18.50 g of pure H2SO4 at a temperature of 25°C.
1.07 g/mL x ?# mL x 0.10 = 18.50 g.0.107ml=18.50g= 172.9ml

The molar conductivity is maximum for the solution of concentration
1) 0.004M
2) 0.002M
3) 0.005M
4) 0.001M
Solution.The molar conductivity of electrolytes increases with decreasing concentration, so the molar conductivity of the solution will be maximum at a concentration of 0.001 M.Answer:4) 0.001 M

A reaction (A- product) is found to be second order in nature. find out its rate constant given the fact that 0.04M of reactants decreases to 0.005M in 10 minutes.
Ans.Rate equation of a second order reaction having initial concentration of the reactant [R]0 and after time t concentration becomes [R] and the rate constant is k1/[R]=kt+1/[R]0For present reaction, [R]...

50% pure 1 g CaCO3 is dissolved in 25 ml H2SO4 solution. A further 30 ml of 0.5 mol NaOH is required for complete dissolution of the mixture. So what was the concentration of H2SO4?
CaCO3 + H2SO4 = H2CO3 + CaSO4H2SO4 + 2NaOH = Na2SO4 + 2H2O1) Active mass of CaCO3 is: 1 g x 0.5 = 0.5 g.n (CaCO3) = m / MM...
