how many grams of solute are needed to order to prepare 100.00 ml of a 0.1000 m solution of a compound with a molecular weight of 350.0 g/mol? report your answer in grams, but do not include units in your answer.

Respuesta :

Molecular Weight - The grams of solute that are needed is 3.5 g.

What is molecular weight?

The mass of the a given molecule is its molecular mass (m), which is expressed in daltons. Because they contain various isotopes of an element, different molecules of same compound can have distinct molecular masses. According to IUPAC, the related quantity comparative molecular weight is a unitless comparison between the mass of a molecule and the truly united atomic mass unit (also called the dalton).

GIVEN:

c =  Molarity = 0.1 M

M = Molar mass = 350 g/mol

V = Volume of solution = 100 mL = 0.1 L

n = Number of moles

m = Mass of solute

C = n/v

n =0.01 moles

M=m/n

m= 3.5g
