Answer:
Mass = 2.12 g
Explanation:
Given data:
Volume of KMnO₄ = 255 mL (255/1000 = 0.255 L)
Molarity = 0.0525 M
Mass in gram = ?
Solution:
First of all we will calculate the number of moles.
<em>Molarity = number of moles of solute / volume in litter</em>
0.0525 M = number of moles of solute / 0.255 L
Number of moles of solute = 0.0525 M ×0.255 L
Number of moles of solute = 0.0134 mol
Mass in gram:
<em>Number of moles = mass/ molar mass</em>
Mass = moles × molar mass
Mass = 0.0134 mol × 158.04 g/mol
Mass = 2.12 g
Answer:
the iron is more condensed then the copper more electricity
Carpenters use nails instead of screws. If that isnt the answer you are looking for than another answer would be that screws hold better than nails. When you screw wood together they don't slide or turn sideways like when you nail wood together. When they are nailed together you can turn the two pieces of wood while they are stuck.
Answer:
depending on the solvent, evaporation would be the easiest
