The number of formula units in 2.50 mol of the compound is 15.1 * 10^23.
The question is unclear whether NaNO2 or NaNO3 is implied. However,in either case, the solution applies equally.
6.02 * 10^23 formula units of the compound are contained in 1 mole
x formula units are contained in 2.5 moles of the compound
x = 6.02 * 10^23 formula units * 2.5 moles/ 1 mole
x = 15.1 * 10^23 formula units of the compound.

Answer:
The Empirical Formula.
Explanation:
From the empirical formula and using the weight (in g) of a given substance, we can come up with the molecular formula which is the actual weight of a substance. Sometimes, we find that the empircal formula is the molecular formula.
Answer:
isomers
Explanation:
Compounds that have the same molecular formula but different chemical structures are called isomers. Remember isomerism is a property between a pair (or more) of molecules, i.e. a molecule is an isomer of another molecule.
Answer:
Momentum
Explanation:
If there is more mass, there is more momentum and if there is more speed there is more momentum. The formula for momentum is mass x speed.
Answer:
The correct answer is 2, 0M
Explanation:
We calculate the molarity, which is a concentration measure that indicates the moles of solute (in this case NaCl) in 1000ml of solution (1 liter):
250 ml solution----- 0,5 moles of NaCl
1000 ml solution----x= (1000 ml solution x 0,5 moles of NaCl)/250 ml solution
x= 2,0 moles of NaCl --> <em>The solution is 2 M</em>
