Answer:
<em>mass of chlorine gas required is 118 kg.</em>
Explanation:
Total mass of the drug (Cisplatin) required = 500 kg
For the drug PtCl2(NH3)2, we first find the molar mass of the compound.
The molar mass of the drug is the total of all the molar mass of the elements in the drug
molar mass of Pt (platinum) in the drug = 195.078 g/mol
molar mass of chlorine (Cl) in the drug = 2 x (35.453 g/mol) = 70.908 g/mol
molar mass of ammonia (NH3) in the drug = 2 x (17.031 g/mol) = 34.062 g/mol
Total molar mass of the drug = 195.078 g/mol + 70.908 g/mol + 34.062 g/mol = 300.048 g/mol
fractional composition of chlorine in the drug = 70.908/300.048 = 0.236
mass of chlorine required for 500 kg of the drug = 0.236 x 500 =<em> 118 kg</em>
Answer:
For these types of questions the equation that we must take into account is that:
T = PxV (where T is the temperature, P is the pressure and V is the volume) this equation is described as we consider that this is the value N and R is 1, therefore it is not necessary to explain them now.
Explanation:
The quoted equation refers to Boyle's Law, in this law we can explain that the volume increases if the pressure decreases and if the temperature also increases, if the pressure increases and the volume decreases this means that the gas is compressing assuming that the temperature is constant
Answer:
V = 0.23 Lt
Explanation:
Data: O₂ 4.50 g = 0.14 mol (considering a molecular mass of 32 g for O₂)
V₁ = 15.0 Lt , T₁ = 203 K , P₁ = 5.0 atm
V₂ = ? , T₂ = 303 K , P₂ = 15.0 atm
If we consider that this gas beahves as an ideal gas, then:
PV = nRT
V = nRT/P
V₂ = nRT₂/P₂ , where R gas constant = 0.082 Lt*atm/K*mol
V₂ = (0.14x0.082x303)/15.0 ⇒ V₂ = 0.23 Lt
Which is consistent, considering that the gas is subjected to a high pressure (from 5 atm to 15 atm), its volume should decrease (from 15 Lt to 0.23 Lt)
The reaction of sodium sulfide with hydrogen sulfide can be shown as
Sodium hydroxide is completely reacting and thus act as limiting reactant
Thus, 2.31 g Na2S produced.
