The chemical formula of barium nitrate is Ba(NO3)2.
The criss-cross method is a technique used to determine the formula of an ionic compound, such as zinc nitrate. Zinc (Zn) has a charge of +2, while the nitrate ion (NO₃) has a charge of -1. By crisscrossing the charges, you take the absolute value of the zinc's charge (2) as the subscript for nitrate and the absolute value of the nitrate's charge (1) as the subscript for zinc. This results in the formula Zn(NO₃)₂ for zinc nitrate.

They cross at the two poles.
First, we need to find the formula for barium nitrate. Barium's charge is 2+, and nitrate is a 1-. If you criss-cross charges, the resulting formula is Ba(NO3)2. Now that we have the formula, we need to find the atomic mass. Barium has an atomic mass of 137. Nitrate is composed of nitrogen (14.01g) and oxygen (16.00*3 = 48). The atomic mass of nitrate is 62.01. Since there are two NO3 molecules, we multiply by 2 to get 124.02. Finally, we add the barium for a grand total of 261.02. Finally, we set-up our conversion ratios: 432 g Ba(NO3)2/1 * 1 mol/261.02g = 1.66 mols
