Answer:
Oasis
Explanation:
An area in the desert that has water in it is called an oasis.
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%.

Argon is the noble gas for titanium
<span>STP signifies standard temperature and pressure.
This conditions are at 1 atmospheric pressure and 0 degrees Celsius. It has
been said that at these conditions, one mole of a gas molecule is equivalent to
22.4 liters of volume. Therefore, the correct answer is the second option which
is 2 L of CH4.</span>
