How many grams of CO2 are in 2.52 mol of CO2?
Show using demential analysis

110.88g

Explanation:

Given parameters:

Mass of CO₂   = 2.52mole

Unknown:

Mass of CO₂ in the given mole  = ?

Solution:

To solve this problem, we use the mole concept.

   Number of moles (mol)  =  

So;

     Mass (g)  = Number of moles(mol) x molar mass(g/mol)

 Molar mass of CO₂   =  12 + 2(16)  = 44g/mol

      Mass(g)  = 2.52 mole x   44g/mole

      Mass(g)  = 110.88g

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
