Answer:
442.3 mL
Explanation:
Remember that Molarity is a measure of concentration in Chemistry and it's defined as the number of moles of the substance divided by liters of the solution:

Then, you can express 11.27 g of AgNO3 as moles of AgNO3 using the molar mass of the compound:

Then you can solve for the volume of the solution:

Answer:
B. Negative ion with a radius larger than the radius of the atom
Explanation:
When a negative ion is formed, electrons are added to the atom. As electrons are added to the atom, the size of the electron cloud increases accordingly.
As a result of this, a negative ion is always larger than its corresponding atom. Hence, nitrogen ion must be larger than the nitrogen atom based on the facts stated above.
Answer:
CaCl2 + 2 AgNO3 ---> 2 AgCl + Ca(NO3)2
