The molarity of KBr solution is 1.556 M
molarity is defined as the number of moles of solute in volume of 1 L solution.
the number of KBr moles in 1 L - 1.556 mol
Therefore in 200.0 L - 1.556 mol/L x 200.0 L = 311.2 mol
Molar mass of KBr - 119 g/mol
mass of Kbr - 311.2 mol x 119 g/mol = 37 033 g
mass of solute therefore is 37.033 kg
thanks for the answers ッ. (btw they’re on the bottom of the question if anyone doesn’t see it.
Answer:
The particles begin to vibrate faster and more.
Explanation:
Adding heat to matter increases the energy, thus creating more movement. Eventually, the bucket will melt, turning to a liquid. While it is a sold, it still has particle movement, just not enough to break volume or shape.
<span>The statement that most accurately and effectively described the polarity and electronegativity in water is that the covalent bonds within these water molecules bind with the single oxygen atom in the molecule, as well as the two hydrogen atoms that it holds as well.</span>
Answer:
78.46 grams of 2-bromopropane could be prepared from 25.5 g of propene
Explanation:
Moles of propene = 
According to reaction, 1 mole of propene gives 1 mole of propane.
Then 0.6538 moles of bromo-propane will give:
78.46 grams of 2-bromopropane could be prepared from 25.5 g of propene.
