The molar mass of co2 is 44.01 g/mole. choose which of the following correctly represents this relationship correctly as a conversion factor. 1 mol co2 = 44.01 g co2 44.01 mol co2 = 1 g co2 44.01 molecules co2 = 1 g co2 1 molecule co2 = 44.01 g co2

The correct answer is : 1 mol of = 44.01 grams of .

Explanation:

Molar mass is defined as the sum of the mass of all the atoms each multiplied its atomic masses that are present in the molecular formula of a compound. It is expressed in g/mol.

n = moles of compound

m = Mass of the compound

M = Molar mass of the compound

We are given with molar mass of carbon dioxide gas which is 44.01 g/mol.

The means that mass of the 1 mole of carbon dioxide gas is 44.01 grams.

n = 1 mole, m =?, M = 44.01 g/mol

So , relationship between molar mass and mass of the carbon dioxide is given as:

1 mol of = 44.01 grams of

answer: semi-infinite solid initially at a uniform temperature of 400 ◦c is cooled at its surface by convection. the cooling fluid at a constant temperature of 200 ◦c has a convective coefficient (ha) of 250 w/m2.k. the physical properties of the solid: k = 20 w/m.k and α = 4 * 10-5  m2/s. using δx = 0.04 m and δt = 10 s. write the finite difference equations describing the transient heat transfer of the first five δx and the temperature profile after 30 s.
