Calculating Mass and Volumetric Flow of Nitrobenzene: Homework Solutions

AI Thread Summary
The specific gravity of nitrobenzene is 1.20, leading to a calculated mass of 300 kg for 250 liters. For a mass flow of 30 lbm/h, the corresponding volumetric flow rate is determined to be 183.33 mL/min. The discussion also addresses the calculation of the density of a mixture containing 20 liters of nitrobenzene and 3 ft³ of benzene, with the specific gravity of benzene being 0.879. To find the mixture's density, the total mass and volume must be calculated and then divided. The conversation emphasizes the importance of understanding specific gravity and volume conversion for accurate density calculations.

Homework Statement



The specific gravity of nitrobenzene is 1.20.
a) Calculate the mass in kg of 250 litres of nitrobenzene.
b) Calculate the volumetric flow in mL/min corresponding to a mass flow of 30 lbm/h of nitrobenzene.
c) Calculate the density of a mixture composed of 20 litres of nitrobenzene and 3 ft^3 of benzene (SG = 0.879), by supposing that the volume of the mixture is the sum of the volume of the two substances.

Homework Equations



SG=p/pref
v=m/p

The Attempt at a Solution


a) I got 1.2*250=300 kg
b) I got v= 183.33 ml/min
C) I do not know how to solve it
I find 3ft^3= 84.950
and I do not how to solve it?Please help me

Thread 'Confusion regarding a chemical kinetics problem'

TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
