What is the mass of 3.75 moles of nacl

mass of 3.75 moles of NaCl =  219.375  grams

Explanation:

Firstly, one need to calculate the molar mass of the compound, sodium chloride. Calculating the molar mass of the compound is adding the atomic mass of each atom present in the compound.

The compound contains 1 atom of sodium and 1 atom of chlorine.

Atomic mass of Na = 23 g

Atomic mass of Cl = 35.5 g

Molar mass of the compound = 23 + 35.5 = 58.5  g per mol

1 mole of NaCl contains 58.5 g

3.75 moles will contain ?

cross multiply

mass of 3.75 moles =  3.75 × 58.5

mass of 3.75 moles of NaCl =  219.375  grams

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.
