Prepare 250 mL of a 0.5 M aqueous sucrose solution. Calculate the mass of sucrose required for the 250 mL solution. The molecular weight of sucrose is 342.3g/mol
M = (w x 1000) / MB x V (ml)
M = molarity of solution = 0.5 M
w = mass of solute = ?
V = volume of solution = 250 ml
MB = molecular mass = 342.3 g/mol
w = M x MB x V (ml) /1000
w = 0.5 x 342.3 x250 /1000
w= 42.788 g
