A jug contais 5L of milk calculate the volume of milk in m cube.....?????? |
|
Answer» Thanks for answering yes.. but if you have any doubt so.. you should wait for another answer. ? ? Is this the answer????r u sure about it???? 1cm\xa0³ = 1 mlas 1 L = 1000mLTherefore1 L = 1000 cm³we know 1 m = 100 cm\xa0= 1 L = 1000 x (10 ^-2 m)³= 10 ^ -3 m\xa0³as the jug contains 5L of milk therefore,5 L = 5x 10³ m³Hence, the jug contains 5 x 10 ^ -3 m³ of milk. |

Find Molality of 30 % w/w h2so4Give with solution |
|
Answer» H2SO4= 98 weight of 30% of H2SO4 soln = 1.218 g = 1000 ml * 1.218 g/ml =1.218g (v*d) wt. of H2SO4 (solute) = 1218*30/100 = 365.4 g wt. of H20 (solvent) = 1218-365.4 now , total wt. of H2SO4 = 365.4+1127 = 1492.4 g 70% of H2SO4 SOln = 1000 ml * 1.61 g/cc =1610g wt. of H2SO4 (solute) = 1610*70/100 = 1127 g wt. of H2O (solvent) = 1610-1127 = 483 g now, tota wt. of H2O (Solvent)= 852.6 + 483 = 1335.6 g finalllllyyyy, molarity = wt*100/molecular wt.* wt. of solvent = 1492.4*1000/98*1335.6 = 11.4 Molality= 30 ×1000/98× 100 =300/98= 3.061 Ans... 11. 4 75÷7 of water |

What is enthalpy? |
| Answer» The total heat content of a system at constant pressure is equal to the sum of the internal energy and PV. This is called the enthalpy of a system which is represented by H.Note that enthalpy is also called as heat content.H = U + pvEnthalpy which depends on the three state functions: internal energy, pressure and volume.Hence it is also a state function.Enthalpy of a substance cannot be measured, but change in enthalpy can be measured.Change in enthalpy = Enthalpy of products - Enthalpy of reactants∆H = HP-HRFrom the first law of thermodynamics∆U =qp-P∆Vqp =heat absorbed by the system-P∆V=work done by the system.For finite changes at constant pressure, ∆H= ∆U+∆(PV)∆H=∆U+P∆V (∵ P is constant ) ∆H=qp ∆H=-Ve for exothermic reactions∆H=+Ve for endothermic reactions. | |
