Which of the following methods is correct for calculating the moles of Al^3+ in 125 mL of 0.234 M Al(NO3)3?
125 mL(1 L/1000 mL)(0.234 mol Al(NO3)3/1 L)(1 mol Al^3+/1 mol Al(NO3)3)
125 mL(1000 mL/1 L)(1 L/0.234 mol Al(NO3)3)(1 mol Al^3+/1 mol Al(NO3)3)
(0.234 mol Al(NO3)3/125 mL)(1000 mL/1 L)(1 mol Al^3+/1 mol Al(NO3)3)
125 mL(1 L/1000 mL)(0.234 mol Al(NO3)3/1 L)(1 mol Al^3+/3 mol Al(NO3)3)
(0.234 mol Al(NO3)3/125 mL)(1000 mL/1 L)(1 mol Al^3+/3 mol Al(NO3)3)
