<span>There
are a number of ways to express concentration of a solution. This includes
molarity and molality. Molarity is expressed as the number of moles of solute per volume of
the solution. MOlality is expressed as moles per kg solution.
5.25 mol H2SO4 / kg solution ( 1 kg / 1000 g ) ( 1.266 g / mL ) ( 1000 mL / 1L ) = 6.6 M H2SO4</span>
Answer:
Molarity = 3.625 M
Explanation:
Given data:
Mass of HCl = 53.0 g
Volume of water = 400.0 mL (400/1000 = 0.4 L)
Molarity of solution = ?
Solution:
Number of moles of of HCl:
Number of moles = mass/ molar mass
Number of moles = 53 g/ 36.5 g/mol
Number of moles =1.45 mol
Molarity:
Molarity = number of moles of solute / volume of solution in L
Molarity = 1.45 mol / 0.4L
Molarity = 3.625 M
Answer:
The top branch-chain is a Isobutane branch. And the bottom branch chain is a Neopentane branch
Yo sup??
since A has a hydroxyl group ie OH therefore it's an alcohol
and since B has an oxygen between two carbons therefore it's an ether.
hence the correct answer is option B
A is alcohol and B is ether
Hope this helps
33.6 moles are needed to completely react with 84.0 moles of O2
