A solution contains 225 g of glucose, C6H12O6, dissolved in enough water to make 0.825 L of solution. What is the molarity of the solution?

Respuesta :

Molar mass glucose : 180.1559 g/mol

number of moles:

n  = mass solute / molar mass

n = 225 / 180.1559 

n = 1.248 moles

therefore:

Molarity  = moles solute / volume 

Molarity =  1.248 / 0.825 => 1.513 M
