Convert 50mL to liters by dividing it by 1000 to get your liters value which should be 0.05 L
Now your formula is .20 = x/0.05
Solve for x to get your mol value and you should get 0.01 mol
Now your formula is .20 = x/0.05
Solve for x to get your mol value and you should get 0.01 mol
Volume = 37.5 mL in liters : 37.5 / 1000 = 0.0375 L
n = M x V
n = 0.445 x 0.0375
n = 0.0166875 moles of solute
Hope I helped!
