0.9 M Al(NO3)3 = 0.9 M *3 M (NO3-) = 2.700 M nitrate ion's (=NO3-)
(Mark the bold numbers: 3above !! because they correspond to e. o.)
Aluminium nitrate is Al(NO3)3. Therefore, for every molecule of aluminium nitrate, there are 3 molecules of nitrates. 0.0525M x 3 is 0.1575M nitrate.
I am assuming that the ratio is in aluminium nitrate, Al(NO3)3. So the ratio of aluminium to nitrate will be 1 : 3.
The concentration of ammonium ion is 32,47 g/L.
1 cubic centimeter is a milliliter. So 5.25 cc = 5.25 mL, or .00525 Liters
loan is 3 year loan with an annual interest of 6.3% and you make monthly payments. Therefore each interest amount will be based on a one month period and thus 1/12 of the annual interest rate. Balance = 10,000 Monthly Interest Rate = 0.525 % 1 months interest = 10,000 * .00525 = $52.50 Your monthly payment is $305.58 Amount applied to balance = 305.58 - 52.50 = $253.08 New Balance = 10,000 - 253.08 = $9,746.92 Next month the interest will be calculated on the new lower balance and your intest payment will be $51.17. so you would have to figure that out by how many pmnts you've made BTW: This doesn't take into account any finance charges, billing charges, etc.
