Calculate the mass (in grams) of 250mL of ether at 25 oC. The density of

leonid [27]

Volume=250mL
Density=0.71g/ml

$\boxed{\sf Density=\dfrac{Mass}{Volume}}$

$\\ \sf{:}\implies Mass=Density(Volume)$

$\\ \sf{:}\implies Mass=0.71(250)$

$\\ \sf{:}\implies Mass=177.5g$

Calculate the enthalpy for the reaction D + F = G + H using

Iteru [2.4K]

The enthalpy for the reaction : ΔH = -132

<h3>Further explanation</h3>

Given

Reaction and the enthalpy

Required

the enthalpy

Solution

Hess Law

Reaction 1 reverse :

A + B = G + C ΔH = -277

Reactions 2 and 3 remain the same (unchanged)

C + F = A ΔH = 303

D = B + H ΔH = -158

Add up all the reactions and remove the same compound from two different sides

D + F = G + H ΔH = -132
