1. Work out the equation and balance
2AgNo3 +BaCl2 ---> 2AgCl + Ba(No3)2
2. Work out formula mass of silver nitrate (should = 169.9)
3. Calculate the number of moles by doing moles = mass / formula mass so 5 divided by 169.9 = 0.0294 moles.
4. Check ratio - here the ratio is 2:2 i.e. 2 moles of silver nitrate to 2 moles of silver chloride so the moles will be the same so the moles of silver chloride is also 0.0294
5. Work out the formula mass of AgCl (always ignore big numbers at the start when working out formula mass) = 143.4
6. Work out mass by doing equation moles = mass/formula mass so
mass = moles x formula mass
mass = 0.0294 x 143.4
mass = 4.22g (3sf or 2dp)
The solution could be described like a saturated and concentrated solution.
<h3>Solutions</h3>
Dissolution of solutions can occur in certain ways. These ways depend on the solvent dilution coefficient and the amount of solute.
If the amount of solute is less than the solvent can dissolve, the solution is unsaturated.
If the amount of solute is exactly the same, the solution is saturated.
If the amount is greater, the solution is supersaturated.
So, since the amount of solute is exactly equal to the amount that the solvent can dissolve, the solution is saturated and concentrated.

The answer is the atomic mass.
Answer:
The answer is that ethane gas has a density of 1.34 g/L at STP
Explanation:
Ethane weighs 0.0013562 gram per cubic centimeter or 1.3562 kilogram per cubic meter, i.e. density of ethane is equal to 1.3562 kg/m³; at 0°C (32°F or 273.15K) at standard atmospheric pressure.
