How many grams are there in 4.5 x 1022 molecules of ba(no2)2?
To find the mass in grams of 4.5 x 10²² molecules of barium nitrate, Ba(NO₂)₂, first determine the molar mass of Ba(NO₂)₂. The molar mass is approximately 199.34 g/mol. Next, convert the number of molecules to moles using Avogadro's number (6.022 x 10²³ molecules/mol): [ \text{moles} = \frac{4.5 \times 10^{22}}{6.022 \times 10^{23}} \approx 0.0747 \text{ moles}. ] Finally, multiply the number of moles by the molar mass to find the mass: [ \text{mass} = 0.0747 \text{ moles} \times 199.34 \text{ g/mol} \approx 14.89 \text{ grams}. ]

When you multiply a positive number by ba negative one what is the sign of the answer?
when you multiply a positive number by a negative number it is a negative. if u multiply a negative by a negative then it is positive
How many moles of oxygen atoms are contained in one mole of BaNO32?
9 moles (there are four oxygen atoms for every mol of BaSO4, so you multiply 2.25 by 4)
What is a procedure for making 100 ml of a 0.10 M solution of barium nitrate?
Ba(NO3)2 Molarity = moles of solute/Liters of solution ( 100 ml = 0.100 liters ) 0.10 M Ba(NO3)2 = moles Ba(NO3)2/0.100 liters = 0.01 moles Ba(NO3)2 (261.32 grams/1 mole Ba(NO3)2) = 2.6 grams of Ba(NO3)2 needs to be put into that 100 milliliters of solution.
How many oxygen atoms does Ba(NO3)2 contain?
Ba(NO3)2 contains a total of 6 oxygen atoms - there are 3 oxygen atoms in each nitrate (NO3) group, and there are 2 nitrate groups in Ba(NO3)2.
How many moles of BaCl2 barium chloride is necessary to react with the 7.5 moles AgNo3 silver nitrate in 2AgNO3 BaCl-- 2AgCl Ba(NO3)2?

How many moles ofBa3(PO4) could be formed from 3.25 moles of Na3PO4 and 7.03 moles of Ba(NO3(2 in the following reaction?
Ba3(PO4) is an incorrect formula. Barium phosphate has the formula 'Ba3(PO4)2 '. So write down the BALANCED reaction eq'n. 2Na3PO4 + 3Ba(NO3)2 = 6NaNO3 + Ba3(PO4)2 The molar ratios are 2:3 :: 6:1 We have 3.25 mol(Na3PO4) equivalent to '2' & 7.03 mol(Ba(NO3)2 ) equivalent to '3' We now must find the limiting reactant. So 3..25 / 2 = 1.625 & 7.03/3 = 2.34333.... We only need 1.625 moles(Na3PO4) to react with 7.03 moles (Ba(NO3)2). So at 3.25 moles the sodium phosphate is in excess. Therefore 7.03 moles barium nitrate is the limiting reactant. By equivalence 3:1 ;; 7.03 : x Hence x /1 = 7.03 / 3 x = 7.03 x 1 / 3 x = 2.34333... moles(Ba(NO3)2) is produced.
What is the mass of one mole of barium nitrate?
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
Ba(NO3)2 contains how many oxygen atoms?
One mole of barium nitrate contains six moles of oxygen atoms. One formula contains 6 atoms.
