Answer:
Ok; first of all, you must correct the Molecular Formula; FeSO4•7H20
So, work out the Molar Mass;,
(4x18)O+ 55.? Iron + 32 Sulphur, PLUS
(7x 18) H2O = 1 molar mass.
Now, take that times 5.24, show your work & check the Mol. Weights, I am going by memory.
Oxygen
Explanation:
Answer: 1 grams C8H18 is equal to 0.0087543811300365 mole.
Explanation:hope i helped:)
EF5 tornado will do more damage than a EF10 tornado because EF10 tornado doesn't even exist.
Answer:
Mass = 3626 g
Number of moles = 37 mol
Explanation:
Given data:
Volume of solution = 2.00 L
Molarity of solution = 18.5 M
Number of moles of solute = ?
Mass of solute = ?
Solution:
Molarity = number of moles / volume in L
By putting values,
18.5 M = number of moles / 2.00 L
Number of moles = 18.5 M × 2 L
Number of moles = 37 mol
Mass of solute:
Mass = number of mole × molar mass
Mass = 37 mol × 98 g/mol
Mass = 3626 g
