Question

experiment if 25000 gram of fuel was completely burnt the heat produced was measured in 225000 kilojoules
calculate the calorific value of the fuel convert into the gram into kilogram​

Answer 1

In what ratio should a 90% solution of H2So4 be mixed with 10% solution of acid to obtain 40% solution?

In what ratio should a 90% solution of H2So4 be mixed with 10% solution of acid to obtain 40% solution?Density = mass/volume.

In what ratio should a 90% solution of H2So4 be mixed with 10% solution of acid to obtain 40% solution?Density = mass/volume.Mass = Density × Volume.

In what ratio should a 90% solution of H2So4 be mixed with 10% solution of acid to obtain 40% solution?Density = mass/volume.Mass = Density × Volume.Given. density = 1g/ml.

In what ratio should a 90% solution of H2So4 be mixed with 10% solution of acid to obtain 40% solution?Density = mass/volume.Mass = Density × Volume.Given. density = 1g/ml.Volume = 2.56 ml.
