Answer:

hydrochloric acid has a molar mass of

36.46 g/mol

, which means that the

164-g

sample will contain

164

g

⋅

1 mole HCl

36.46

g

=

4.498 moles HCl

As you know, molarity is defined as moles of solute, which in this case is hydrochloric acid, divided by liters of solution

molarity

=

liters of solution

A

6.0-M

hydrochloric acid solution will contain

6

moles of hydrochloric acid for every liter of solution. This means that

4.498

moles will come with a volume of

The number of moles of hydrochloric acid in 10 mL of 6.0 M HCI is 0.06 mol.

Number of moles of the hydrochloric acid

The number of moles of hydrochloric acid in 10 mL of 6.0 M HCI is claculated as follows;

Molarity = number of moles / Volume of the solution (L)

where;

  • volume of the hydrochloric acid  = 10 mL = 0.01 L
  • Molarity of the hydrochloric acid  = 6 M

Number of moles = 0.01 x 6

Number of moles = 0.06 mol.

Thus, the number of moles of hydrochloric acid in 10 mL of 6.0 M HCI is 0.06 mol.
