How many moles of oxygen are in 1.6 mol of ca(no3)2?

Answer : The moles of oxygen are, 9.6 moles.

Explanation : Given,

Moles of = 1.6 mole

As we know that,

In , there are 2 atoms of nitrogen, 1 atom of calcium and 6 atom of oxygen.

Now we have to calculate the moles of oxygen.

As, 1 mole of contains 6 moles of oxygen.

So, 1.6 moles of contains moles of oxygen.

Therefore, the moles of oxygen are, 9.6 moles.

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.

put the answers   and i could answer.
