Answer:
16.54 mL
Explanation:
From the question;
- Density of mercury of 13.6 g/mL
- Mass of the mercury metal is 225 g
We are needed to determine the volume of the mercury metal;
We need to know that;
- Density is given by dividing the mass of a substance by its volume.
That is;
Density = Mass ÷ Volume
Rearranging the formula;
Volume = Mass ÷ Density
Therefore;
Volume = 225 g ÷ 13.6 g/mL
= 16.54 mL
Thus, the volume of the mercury needed is 16.54 mL
Answer:
it is the same way it is purified in the state
3.75 litres is the volume of the balloon indoors at a temperature of 25°C.
Explanation:
Data given:
initial temperature of the gas in balloon = -35°C or 238.15 K
initial volume = 3 litres
final temperature = 25 °C or 298.15 K
final volume =?
pressure remains constant
From the data given when pressure is constant Charles' law is applied.
= 
Rearranging the equation to know the final volume of the gas in balloon
V2 = 
V2 = 
V2 = 3.75 Litres
when the temperature of a gas is increased and pressure remains constant the volume of the gas increases.
