Consider this question: What is the molarity of KMnO4 in a solution of 0.0908 g of KMnO4 in 0.500 L of solution?

natita [175]

Answer:

0.0011 M.

Explanation:

Molarity of a substance , is the number of moles present in a liter of solution .

M = n / V

M = molarity

V = volume of solution in liter ,

n = moles of solute ,

Moles is denoted by given mass divided by the molecular mass ,

Hence ,

n = w / m

n = moles ,

w = given mass ,

m = molecular mass .

From the question ,

w = given mass of KMnO₄ = 0.0908 g

and ,

V = 0.500 L

Since ,

we know ,

m = Molecular mass of KMnO₄ = 158 g/mol

using , the above formula to calculate the moles ,

n = w / m = 0.0908 g / 158 g/mol = 0.00057 mol

now , calculating the molarity as ,

M = n / V = 0.00057 mol / 0.500 L = 0.0011 M.

Bam added 5.42 g of cscl to 35.31 ml of h2o. calculate the concentration of bam's solution in units of g solute/100 g solvent. m

Brums [2.3K]

Bam's solution, 5.42 g of CsCl mixed with 35.31 ml of H2O, has a concentration of 15.3882 g CsCl/100 g H2O.

Concentration, in chemistry, is defined as the amount of solute in a particular amount of solvent or solution. Some of the most common ways to express concentration includes molarity, mass-to-mass and mass-to-volume.

To solve for the concentration of Bam's solution in g solute/100 g solvent, solve for the mass of the solvent first.

To solve for the mass of the solvent, use the density and volume:

mass solvent = density x volume

mass solvent = 0.9975 g/ml x 35.31 ml

mass solvent = 35.221725 g

Solving for the concentration of Bam's solution in g solute/100 g solvent, where the mass of the solute CsCl is 5.42 g:

concentration = mass solute/ 100 g solvent

concentration = 5.42 g/ (35.221725/100)

concentration = 15.38822985

concentration = 15.3882 g CsCl/100 g H2O
