A chemist has 3.55x1022 molecules of nitrogen monoxide. How
Alina [70]

Answer:

<h2>0.059 moles</h2>

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

n =  \frac{N}{L} \\

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

n =  \frac{3.55 \times  {10}^{22} }{6.02 \times  {10}^{23} }  \\  = 0.05897...

We have the final answer as

<h3>0.059 moles</h3>

Hope this helps you

The gravitational force between which two objects would be the most difficult to notice? A. The moon and the earth b. The moon a
Ghella [55]

Answer:

d. A water particle and an air particle

Explanation:

The force of gravity (F) between two objects of masses m1 and m2 and separated by a distance r is given as:

F = G\frac{m1*m2}{r^{2} }

where G is the gravitational constant

This force is therefore, directly proportional to the masses and inversely related to the distance between them.

Based on the given options, since the masses of the water and air particles are very small (masses of earth, moon and sun is relatively huge), the gravitational force between them would be negligible and difficult to measure.
