The molarity of her solution will be 1.88 M

<h3>What is Molarity ?</h3>

Molarity is defined as the number of moles of solute dissolved in per litre of solution.

Molarity of the solution = number of moles of solute / volume of solution in litre

number of moles of solute = given weight / molecular weight

                                            = 43.3 / 45.95

                                            = 0.942 moles

Now, lets calculate Molarity ;

Molarity of the solution = number of moles of solute / volume of solution in litre

                                       = 0.942 / 0.500

                                       = 1.88 M

Hence, The molarity of her solution will be 1.88 M

Answer: 0.714 moles of PbI_2 will be produced from 237.1 g of potassium iodide

Explanation:

To calculate the moles :

\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}    

\text{Moles of potassium iodide}=\frac{237.1g}{166g/mol}=1.428moles

The balanced chemical reaction is:

Pb(NO_3)_2+2KI\rightarrow PbI_2+2KNO_3

According to stoichiometry :

2 moles of KI produce =  1 mole of PbI_2

Thus moles of KI will require=\frac{1}{2}\times 1.428=0.714moles  of PbI_2

Thus 0.714 moles of PbI_2 will be produced from 237.1 g of potassium iodide

Volume of 1 mole of N2 at 30 c and 1.2 ATM
Mariana [72]
We should indicate first and foremost the assumption of ideal gas behavior so that we can use the ideal gas equation written below:

PV = nRT

For this problem,let's solve for V. Rearranging the equation,

V = nRT/P

Substituting the values,

V = (1 mol)(0.0821 L-atm/mol-K)(30 + 273 K)/1.2 atm
<em>V = 20.73 L of N₂ gas</em>
