If the mass ratio of nitrogen to hydrogen in ammonia is 4.7:1. if a sample of ammonia contains 10.0 gram of h, how many grams of

n does it contain?

The amount, in grams, of N that the sample will contain will be 2.1 grams.

<h3>Stoichiometric mass ratio</h3>

According to the problem. the mass ratio of H and N in ammonia is 4.7:1.

In other words, every 4.7 grams of H in ammonia must have 1 gram of N.

Now, in a particular ammonia sample, 10 grams of H is present.

The amount of N present can be calculated from the standard mass ratio.

4.1 grams H = 1 gram N

10 grams H = x

4.1x = 1 x 10

        x = 10/4.1

             x = 2.1 grams

Thus, the mass of nitrogen in the ammonia sample will be 2.1 grams.

The difference between the density of gas and the density of liquid
eduard

The molecules of a liquid substance are closely packed together to each other. So as a result, liquids are denser than gases.

<h3>What is the difference between the density of liquid and gas?</h3>

A mass of gas will have a much larger volume compared to the same mass of liquid. This is because it has a much lower density. The density of gaseous oxygen is 0.0014 g/cm3. Density is ρ=Mass Volume. We know that gas will uniformly occupy more space than liquid whatever volume is available to it. On the other hand, solids and liquids, are closely packed as compared to gas and are high-density materials where ρ is relatively constant.

So we can conclude that the molecules of a liquid substance are closely packed together with each other. So as a result, liquids are denser than gases.

How much energy does an X-ray with an 8 nm (8 x 10-9 m) wavelength have?
Vlada [557]

Answer: 2.48×10^-17 J

Explanation:

Given the following :

Wavelength = 8nm (8 x 10^-9 m)

Energy(e) of X-ray =?

Energy=[speed of light(c) × planck's constant (h)] ÷ wavelength

Speed of light = 3×10^8m/s

Planck's constant = 6.626×10^-34 Js

Wavelength = 8 x 10^-9 m

Energy = [(3×10^8) * (6.626×10^-34)] / 8 x 10^-9

Energy = [19.878×10^(8-34)] / 8 x 10^-9

Energy = 2.48475 × 10^(-26+9)

Energy = 2.48×10^-17 J

When KNO3 dissolved in water, what is the intermolecular attraction between NO3 ions
Snezhnost [94]
Ion-dipole forces

H2O has hydrogen bonding, which is a form of dipole-dipole forces, and NO3- is an ion, so the intermolecular attraction is ion-dipole.
