Repeated patterns in the elements.
Hopefully this helps
Answer:
Osmium, 22.6 g/cc.
Iridium, 22.4 g/cc.
Platinum, 21.45 g/cc.
Rhenium, 21.2 g/cc.
Uranium, 20.2 g/cc.
these are are metals having a high density
Explanation:
Moles of ammonia is 2.4 moles
Molarity of solution after dilution is 2.4 M
Given:
volume of ammonia solution = 0.40 l
molarity of solution = 6.00 m
To Find:
moles of ammonia
Solution:
1 molar (M) solution will contain 1.0 GMW of a substance dissolved in water to make 1 liter of final solution
M = n / V
M is the molality of the solution that is to be calculated
n is the number of moles of the solute
V is the volume of solution given in terms of litres
n = M x V
= 6 x 0.4
= 2.4 moles
So moles of ammonia are 2.4 moles
molarity of the resulting solution after dilution
M = n/V
= 2.4/1
= 2.4 M
So Molarity after dilution will be 2.4 M
