Answer: M= 128 g/mol (Te is quite close)
Explanation: number of Oxygen moles is n = 8 g / 32 g/mol = 0,25 mol.
Because formula of oxide is MO, thus amount of metal is also 0,25 mol.
Because n = m/M , Molar mass of the metal M = m/n = 32 g /0.25 mol = 128 g/ mol
<h2>Question:</h2>
- A solution that is able to dissolve additional solute is best described as _____.
<h2>Answer:</h2>
<h2>D.) Unsaturated </h2>
- <u>Unsaturated</u> means the substance is poured into the solvent that can be dissolved. It is a solution (with less solute than the saturated solution) that completely dissolves, leaving with no remaining substances.
<h2>For example:</h2>
- If you were to pour olive oil into a glass of water, it will dissolve, so it is <u>unsaturated</u>.

Hey There!
Assuming the part of the round flask containing liquid to be perfect sphere, we can calculate it's volume.
Given diameter of sphere = 24 cm
Therefore radius of the sphere, r= 24/2= 12 cm
Volume of the sphere of diameter 24 cm = (4/3)*pi*r³ = 7,238.23 cm3
Conversion of cm³ to L
1 L= 1 dm³
1 dm = 10 cm
Therefore 1L= 1 dm³ = 1000 cm³
So the volume of liquid in the round flask = 7.24 L( round of to nearest 0.01 L)
Answer:
Explanation:
1 Mole of Aluminum with mass 26.98g contains 6.02*10^23 atoms.
In 2.88g of Aluminum, there are 2.88/26.98*6.02*10^23 = 6.426*10^22 atoms.
Water, Water is not a pure substance. It is a mixture, and Chromatography
