Answer:

=0.15M

Explanation:

To get the moles of the unknown LiOH, calculate the number of moles of HCl in 12.3mL.

Using the stoichiometric coefficient, mole ratio 1:1.

This means that the number of moles is the same. This number of moles is contained in 18mL. Then Calculate the molarity (concentration) which is in 1000mL

See the explanation from the image I have shared with you for calculations.

A reaction at −8.0°C evolves 854.mmol of boron trifluoride gas. Calculate the volume of boron trifluoride gas that is collected.
Bas_tet [7]

Answer:  The volume of boron trifluoride gas that is collected is 18.6 L

Explanation:

According to the ideal gas equation:

PV=nRT

P = Pressure of the gas = 1 atm

V= Volume of the gas= ?

T= Temperature of the gas in kelvin =-8.0^0C=273+(-8.0)=265K

R= Gas constant = 0.0821Latm/Kmol

n=  moles of gas=  854 mmol = 0.854 mol   (1mmol=0.001mol)

1atm\times V=0.854\times 0.0821\times 265

V=18.6L

Thus volume of boron trifluoride gas that is collected is 18.6 L
