Answer:
V = 134.5 L
Explanation:
Given data:
Number of moles of KClO₃ = 4 mol
Litters of oxygen produced at STP = ?
Solution:
Chemical equation:
2KClO₃ → 2KCl + 3O₂
Now we will compare the moles of KClO₃ with oxygen.
KClO₃ : O₂
2 : 3
4 ; 3/2×4 = 6 mol
Litters of oxygen at STP:
PV = nRT
V = nRT/P
V = 6 mol × 0.0821 atm.L/mol.K × 273 K / 1atm
V = 134.5 L / 1
V = 134.5 L
Explanation :
The balanced chemical reaction will be,
![3CuO(s)+2NH_3(g)\rightarrow 3Cu(s)+N_2(g)+3H_2O(l)](https://tex.z-dn.net/?f=3CuO%28s%29%2B2NH_3%28g%29%5Crightarrow%203Cu%28s%29%2BN_2%28g%29%2B3H_2O%28l%29)
By the stiochiometry, 3 moles of solid copper(II)oxide react with 2 moles of ammonia gas to give 3 moles of copper metal, 1 mole of nitrogen gas and 3 moles of liquid water.
The states of matter of each elements and compound is,
Copper(II)oxide is in solid state
Ammonia is in gaseous state
Copper metal is in solid state
Nitrogen is in gaseous state
Water is in liquid state

The prescription in mg/Kg of body weight is 5.62 mg/kg.
<h3>How to convert to mg required per kg of body weight?</h3>
Drugs are chemicals that are taken into the body and they are able to help to correct anomalies in the bodies. Drugs are taken according to the kind of ailment that a person is suffering from.
The nature of the drug and the severity of thee ailment of the person determines the dose of the drug.
Now we know that;
1 g/pound =2204.6244 mg/kg
0.00255g/lb = 0.00255g/lb * 2204.6244 mg/kg/1 g/pound
= 5.62 mg/kg
