Because ionic compounds' strong bonds form network structures, which have a stronger attraction than the covalent compounds which are molecules.
Hi Soccerbrandon,
So in order to do unit conversion in this situation, it is best to first convert kg into g and then g into mg. The conversion rates are easy to remember individually for both of them.
There are 1000 g in 1 kg.
There are 1000 mg in 1 g.
So lets use 25 kg as an example:
25 kg times

gives 25000 g in 25 kg.
25000 g times

gives 25000000mg in 25000g.
This gives us the answer that 25000000mg is equal to 25kg.
Hope it helps!!
Answer:
2.82 g
Explanation:
Step 1: Write the balanced precipitation reaction
3 Ba(NO₃)₂ (aq) + Al₂(SO₄)₃ (aq) ⇒ 3 BaSO₄(s) + 2 Al(NO₃)₃(aq)
Step 2: Calculate the reacting moles of Ba(NO₃)₂
45.0 mL (0.0450 L) of 0.548 M Ba(NO₃)₂ react.
0.0450 L × 0.548 mol/L = 0.0247 mol
Step 3: Calculate the moles of Al₂(SO₄)₃ that react with 0.0247 moles of Ba(NO₃)₂
The molar ratio of Ba(NO₃)₂ to Al₂(SO₄)₃ is 3:1. The reacting moles of Al₂(SO₄)₃ are 1/3 × 0.0247 mol = 8.23 × 10⁻³ mol
Step 4: Calculate the mass corresponding to 8.23 × 10⁻³ moles of Al₂(SO₄)₃
The molar mass of Al₂(SO₄)₃ is 342.2 g/mol.
8.23 × 10⁻³ mol × 342.2 g/mol = 2.82 g
