What is the molarity of 70.6 g C2H6O in 2.25 L of solution
myrzilka [38]

Hey there!

Molar mass C2H6O = 46.0684 g/mol

Number of moles:

n = mass of solute / molar mass

n = 70.6 / 46.0684

n = 1.532 moles

Therefore:

M = number of moles / volume ( L )

M = 1.532 / 2.25

= 0.680 M

Hope that helps!

Number the steps for balancing equations:
adelina 88 [10]

Answer:

identify the atoms on each side.

Count the atoms on each side.

Use coefficients to increase the atoms on each side.

Check to make sure you have the same number of each type of atom on each side.

Explanation:

The concept behind balancing chemical equations is to ensure that they comply with the law of conservation of matter. This helps to make chemical equations quantitatively meaningful.

  • First, identify the atoms on each side of the expression.
  • Then count these atoms.
  • Assign appropriate numeric coefficient to the species.
  • Then check to make sure there are equal number of each type of atoms on each side.

The subscript of the formula must not be changed in an attempt to balance a chemical equation.
