How many grams of n are in 82.0g of nh2no3?

29.44 grams

Explanation:

Molar Mass of NH2NO3 = Molar Mass of Nitrogen + 2(Molar Mass of Hydrogen) + Molar Mass of Nitrogen + 3(Molar Mass of Oxygen)

Molar Mass of NH2NO3 = 14 + 2(1) + 14 + 3(16) = 78 grams

Mass of Nitrogen in NH2NO3 = 14 + 14 = 28 grams

Percentage by mass of Nitrogen in NH2NO3 =

This means, the percentage of Nitrogen in NH2NO3 is 35.90%. So the amount of Nitrogen in 82 g of NH2NO3 will be 35.90% of 82

35.90% of 82 = 0.359 x 82 = 29.44 grams.

Thus, 29.44 grams of Nitrogen will be present in 82 grams of NH2NO3

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.
