 Convert the following to moles.
Luda [366]
Use dimensional analysis.
\frac{60.0 grams NaOH}{1} *  \frac{1 mole NaOH}{40.0 amu NaOH} =1.5 moles

\frac{2.73 grams NH4Cl}{1} *  \frac{1 mole NH4Cl}{53.49 amu NH4Cl} = .051 moles

Now you try converting moles to grams. All you have to do is start with MOLES  (Unlike the previous examples) over 1 then multiply that ratio by the ratio of molar mass over 1 mole. Hope this helps!

In an electron dot diagram of propane (C3H8), how many double bonds are present?
NeX [460]

Answer:- none

Explanations:- For naming hydrocarbons we use the suffix -ane, -ene and -yne.

-ane is used when we have only single bonds between all carbons. -ene is used if there is any double bond between two carbons and the -yne is used if there is any triple bond between two carbons.

The given name of the compound is propane. It ends at -ane and so it's an alkane and must have single bonds between all the carbons it has. So, there are zero double bonds present in C_3H_8 .

This is also clear from the below lewis dot structure of the compound.
