Aliquid that occupies a volume of 2.68 l has a mass of 2.40 kg what is the density of the liquid in kgl/?

Answer : The density of the liquid is, 0.895 g/ml

Explanation : Given,

Volume of liquid = 2.68 L = 2680 ml

Mass of liquid = 2.40 Kg = 2400 g

Conversion used :

1 L = 1000 ml

1 Kg = 1000 g

Formula used :

Now put all the given values in this formula, we get density of liquid.

Therefore, the mass of the liquid is, 0.895 g/ml

answer : third trial had the contaminated sample and the correct value for dhrxn should be 1000 kj/mol

explanation :

let us write down the given equations

equation 1 :

equation 2 :

equation 3 :

let us use hess's law to find out which 2 equations can be added to get the third equation.

let us reverse equation 2 and multiply it by 2. the new equation that we get is,

equation 4 :

let us add equation 1 & 4

the above equation is similar to equation 3 but has different value for dhrxn.

therefore third trial had the contaminated sample and the correct value for dhrxn should be 1000 kj/mol
