Elements in the same group have the same amount of electrons, this affects bonding because it determines how much the element will "want" to form a covalent bond.
Answer:
warm water is denser than cold water
Explanation:
First convert mega grams to grams
(9.57x10^2)*(10^6)=957100000 grams
Then find the molar mass of nickel sulphate
Nickel Ni 3+ and sulphate SO4 2+
So formula= Ni2(SO4)3
So mr = (59*2) + (32*3) + (16*12)
= 406gmol-1
Moles = mass/mr
957100000/406
=2357389.163 moles
Answer:
Molarity = 0.01 M
Explanation:
Molarity is used to measure the concentration of a solution. It will be same for the whole solution or a small amount of solution if the solution is homogeneous.
So, <u>Molarity of 200 mL of solution = Molarity of 50 mL of solution</u>


given mass of aspirin = 360 mg = 0.36 g
molar mass of aspirin = 180 g
Volume of solution = 200 mL = 0.2 L


Therefore, Molarity = 0.01 M
