A biochemical engineer isolates a bacterial gene fragment and dissolves a 10.0-mg sample in enough water to make 30.0 mL of solu
Novay_Z [31]

The molar mass of the gene fragment is 19182 g/mol.

What is osmotic pressure ?

Osmotic pressure is the minimum pressure which needs to be applied to a solution to prevent the inward flow of its pure solvent across a semipermeable membrane. It is also defined as the measure of the tendency of a solution to take in a pure solvent by osmosis. Potential osmotic pressure is the maximum osmotic pressure that could develop in a solution if it were separated from its pure solvent by a semipermeable membrane.

We employ the osmotic pressure equation to determine the solute's concentration, which is:

π = iMRT

Using the values in the equation above, we obtain:  19182 g/mol.

The molecule CCI4 contains one double bond and three single bonds. True or False
kifflom [539]

False

Explanation: Carbon is the central atom which has valency of 4 and can form 4 bonds to complete its octet. Each chlorine has valency of 1 and can form only one bond to complete its octet. Thus carbon can bond with four chlorine atoms through sharing of electrons to form four single bonds. Thus it cannot contain a double bond.

Which one of these compounds is an ionic compound? question 18 options: n2 na2o co2?
spayn [35]

Types of Bonds can be predicted by calculating the difference in electronegativity.

If, Electronegativity difference is,

 

                Less than 0.4 then it is Non Polar Covalent

                

                Between 0.4 and 1.7 then it is Polar Covalent 

            

                Greater than 1.7 then it is Ionic

 

For N₂,

                    E.N of Nitrogen      =   3.04

                    E.N of Nitrogen      =   3.04

                                                   ________

                    E.N Difference             0.00         (Non Polar Covalent)

For Na₂O,

                    E.N of Oxygen       =   3.44

                    E.N of Sodium       =   0.93

                                                   ________

                    E.N Difference             2.51         (Ionic)

For CO₂,

                    E.N of Oxygen       =   3.44

                    E.N of Carbon       =    2.55

                                                   ________

                    E.N Difference             0.89         (Polar Covalent)
