How many grams of MgCl2 are in 2.14 moles of MgCl2?

203.752 grams

Explanation:

-The molar mass of is 95.211 g/mol

-Let X be the mass of in grams.

-Given 2.14 moles of , we convert into grams as follows:

Hence, there are 203.752 grams of in 2.14moles of MgCl2

there all right good

explanation:

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
