Answer: 31! hope this helps!
Explanation:
Answer:
Mass = 96g
Explanation:
Molarity = number of moles/volume of solvent
According to the provided information, volume = 1.55L, Molarity = 1.55M
number of moles (n) = molarity × volume
n = 1.55 × 1.55
n = 2.4025
n = 2.40mol
For NaOH, molar mass = 23 + 16 + 1 = 40g/mol
mole = mass/molar mass
Mass = molar mass × mole
Mass = 40 × 2.40
Mass = 96g
QUËSTIONS :- what are the difference between ionic bond and covalent bond?
IONIC BONDS :- THEY R BONDS WHICH R FORMED DUE TO THE COMPLETE TRANSFER OF ELECTRONS BETWEEN TWO ATOMS
COVALENT BONDS :- THEY R THE BONDS WHICH R FORMED DUE TO INCOMPLETE TRANSFER OF ELECTRONS BETWEEN TWO ATOMS
IONIC BONDS R MORE STRONGER.
It does that because petrol is a liquid chemical,has a lower mass per volume,or density,then the water on top so it spread out on top of the water
