How many moles of ions will be present in 716 ml of 0.450 m solution of sodium phosphate(aq)?

Number of moles of ions in 0.716 L of 0.450 M solution is 1.2888 moles.

Solution:

Volume of the solution 716 mL

Molarity of the solution : 0.450 M

According to reaction one mol is giving 4 moles of ions.

Number of moles of ions in 0.716 L of 0.450 M solution is =

Hence,number of moles of ions in 0.716 L of 0.450 M solution is 1.2888 moles.

why is arctic sea ice important? arctic sea ice keeps the polar regions cool and moderate global climate. sea ice has a bright surface; 80 percent of the sunlight that strikes it is reflected back into space. as sea ice melts in the summer, it exposes the dark ocean surface.
