Question 6 Use the mole concept to calculate the number of formula units that are in a 1.75-mol sample of NaCl.

There are formula units in 1.75 mol sample of NaCl.

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number of particles.

1 mole of NaCl contains = formula units

Thus 1.75 mol of NaCl contains = formula units

Thus there are formula units in 1.75 mol sample of NaCl.

in cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level. a contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes.

explanation:

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.
