It is the the curved upper surface of a liquid in a tube.
Answer:
1.06L = V₂
Explanation:
Charle's Law states that the volume of a gas is directly proportional to the absolute temperature when pressure remains constant.
The equation is:
V₁T₂ = V₂T₁
<em>Where V is volume and T absolute temperature of 1, initial state and 2, final state of the gas.</em>
V₁ = 1.83L
T₂ = -100°C + 273.15 = 173.15K
V₂ = ?
T₁ = 27°C + 273.15 = 300.15K
V₁T₂ = V₂T₁
1.83L*173.15K = V₂*300.15K
<h3>1.06L = V₂</h3>
The concentration in weight percent when 6 g of sugar is mixed with 9 g of water is 40%.
There are several ways to denote the concentration of a solution like
- Molarity
- Molality
- Mass percent
- Mole Fraction
The formula for calculating mass percent is as follows
Mass per cent = (Mass of solute/Mass of solute + Mass of solvent) x 100%
In the given situation sugar is the solute and water is the solvent.
Putting the given values in the above formula
Mass per cent = (6/6+9) x 100%= 6/15 x 100% = 40%
Hence, the concentration in weight percent when 6 g of sugar is mixed with 9 g of water is 40%.
