How many grams of sodium chloride are present in a 0.75 m solution with a volume of 500.0 milliliters?

-

219.375 g of NaCl is present in a 0.75 M solution with a volume of 500.0 milliliter

Explanation: -

Volume of NaCl solution = 500 mL

= 500/1000 = 0.5 L

Strength of NaCl solution = 0.75 M

Number of moles of NaCl = Strength of NaCl x Volume of NaCl

= 0.75 M x 0.5 L

= 3.75 mol

Molar mass of NaCl = 23 x 1 + 35.5 x 1

= 58.5 g / mol

Mass of NaCl = Molar mass x number of moles

= 58.5 g / mol x 3.75 mol

= 219.375 g

thats a little if u want the answer just look it up on google thats what i do haha : )

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.
