14.2g
80.38
11.2 g
32.9 g

The mass of sodium chloride in 219 g solution is 32.9 g

Explanation:

To calculate the mass percent of element in a given compound, we use the formula:

To find mass of sodium chloride in solution:

Mass percent of sodium chloride= 15.0 %

Mass of solution = 219g

Thus mass of sodium chloride in 219 g solution is 32.9 g

water at room temperature is flowing through a pipe with pressure taps located 10 ft apart along one section of the pipe, which are connected to a mercury (s=13.6) manometer.
