Answer:
1.42 L
Explanation:
Step 1:
The following data were obtained from the question :
Molarity of KBr = 2.40 M
Mole of KBr = 3.40 moles
Volume of solution =?
Step 2:
Determination of the volume of the solution.
Molarity of solution is simply the mole of the solute per unit volume the of solution. It is given as :
Molarity = mole /Volume
Volume = mole /Molarity
Volume = 3.4/2.4
Volume = 1.42 L
Therefore, the volume of the solution is 1.42 L
Answer:
mass = 508 g
Explanation:
Given data:
Number of moles of Cu = 8 mol
Mass in gram = ?
Solution:
Number of moles = mass/molar mass
Molar mass of Cu is 63.5 g/mol.
Now we will put the values in formula.
8 mol = mass /63.5 g/mol
mass = 63.5 g/mol
×8 mol
mass = 508 g

Answer:
C. Nonpolar covalent
Explanation:
The type of bond that holds hydrogen(H) atoms together in a molecule of hydrogen is a non-polar covalent bond.
- A covalent bond forms between two atoms with low or zero electronegativity difference.
- It is usually between non - metals or atoms of the same kind.
- When atoms of the same kind bonds as in hydrogen to form hydrogen gas, non-polar covalent bond is formed.
- This is because there is no charge separation.
