A gas evolved during the fermentation of sugar was collected at 22.5°C and 702 mmHg. After purification its volume was found to
miskamm [114]

Answer:

A) 0.95 mol

Explanation:

We will assume the gas given off in the fermentation is an ideal gas because that allows us to use the ideal gas equation.

PV  = nRT

First let's convert all measurements to units that we can use

P = 702 mmHg * 1 atm/760 mmHg = 0.92368 atm

V = 25.0 L

R = 0.08206 L-atm/mol-K

T = 22.5 °C +273.15 = 295.65 K

PV  = nRT

0.92368 atm * 25.0 L = n * 0.08206 L-atm/mol-K * 295.65 K

                                  n = 0.9518 mol

A sample of ideal gas at room temperature occupies a volume of 12.0 L at a pressure of 802 torr . If the pressure changes to 401
Blababa [14]

 The new  volume  is  2.4 L

<u><em> calculation</em></u>

The new volume is calculated using Boyle's  law formula

That  is  P₁V₁=P₂V₂

where,

p₁ =  802 torr

V₁ = 12.0 l

P₂ = 4010 torr

V₂=?

make  V₂ the subject of the formula  by diving  both side of equation by P₂

V₂ = P₁V₁/P₂

V₂  is therefore = {(12.0 l × 802 torr) 4010 torr}  = 2.4 L
