How many moles are in 1.93x1023 particles of Na3PO4?
2 answers:
Answer:
<h3>The answer is 0.32 moles</h3>Explanation:
To find the number of moles given the number of entities we use the formula
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question
N = 1.93 × 10²³ particles
We have
We have the final answer as
<h3>0.32 moles</h3>Hope this helps you
<h3><u>Answer</u> :</h3>
No. of particles of Na₃PO₄ = 1.93×10²³
We have to find number of moles of the given compound
Number of moles cam be found by using this formula :
- n denotes number of moles
- N denotes number of particles
denotes avogadro's constant
We know that,
= 6.022×10²³
★ <u>Calculation</u> :
➠ n = N/
➠ n = (1.93×10²³)/(6.022×10²³)
➠ <u>n = 0.32 moles</u>
★ <u>Explore More</u> :
- n = weight / Molar mass
- n = volume / 22.4

Reactant C is the limiting reactant in this scenario.
Explanation:
The reactant in the balanced chemical reaction which gives the smaller amount or moles of product is the limiting reagent.
Balanced chemical reaction is:
A + 2B + 3C → 2D + E
number of moles
A = 0.50 mole
B = 0.60 moles
C = 0.90 moles
Taking A as the reactant
1 mole of A reacted to form 2 moles of D
0.50 moles of A will produce =
thus 0.50 moles of A will produce 1 mole of D
Taking B as the reactant
2 moles of B reacted to form 2 moles of D
0.60 moles of B reacted to form x moles of D
=
x = 2 moles of D is produced.
Taking C as the reactant:
3 moles of C reacted to form 2 moles of D
O.9 moles of C reacted to form x moles of D
=
= 0.60 moles of D is formed.
Thus C is the limiting reagent in the given reaction as it produces smallest mass of product.
Explanation:
For the given reaction:
Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.
where x and y are order wrt to and
According to collision theory , the molecules must collide for a reaction to take place. According to collision theory , the rate of a reaction is proportional to rate of collision of reactants.
Thus with an increase in concentration of reactants , the rate of reaction also increases. This is because if the concentration of reactants increases , the chances of collision between molecules also increases and thus more products wil be formed which in turn increases the rate of reaction.
