Gas sample has a volume of 0.287 L with an unknown temperature. The same gas has a volume of 0.180 L when the temperature is 37∘
Nat2105 [25]

Answer:

205.3°C

Explanation:

Given parameters:

V₁   =  0.287L

V₂ = 0.18L

T₂  = 37°C

Unknown:

T₁  = ?

Solution:

Since we are interested in volume and temperature relationships in a fixed pressure of the balloon, Charles's law will be a perfect solution to this problem.

Charles's law states that "At constant pressure, the volume of a fixed mass of gas is directly proportional to its temperature".

Mathematically;

                   \frac{V_{1} }{T_{1} }  = \frac{V_{2} }{T_{2} }

where V and T are volume and temperature of the gas

              1 and 2 are initial and final states;

let us convert T₂  = 37°C to K;  37 + 273  = 300K

 Input the parameters and solve for the unknown;

               \frac{0.287}{x}   = \frac{0.18}{300}

               T₁  = 478.3K

Now convert back to °C;    478.3  - 273   = 205.3°C

What mass of hydrogen gas is displaced when 6.0 mol of iron react with excess
Nonamiya [84]

18 g of hydrogen gas

Explanation:

We have the following chemical reaction:

2 Fe + 6 HCl → 2 FeCl₃ + 3 H₂

Knowing the stoichiometry of the chemical reaction, we devise the following reasoning:

if        2 moles of iron react produces 3 moles of hydrogen

then   6 moles of iron react produces X moles of hydrogen

X = (6 × 3) / 2 = 9 moles of hydrogen

mass = number of moles × molecular weight

mass of hydrogen (H₂) = 9 × 2 = 18 g

number of moles
