kogti [31]

Answer:

Solids, liquids, and gases are made of tiny particles called atoms and molecules. In a solid, the particles are very attracted to each other. They are close together and vibrate in position but don't move past one another. In a liquid, the particles are attracted to each other but not as much as they are in a solid.

What does it mean for a element of a group to have a order?
lisabon 2012 [21]

In group theory, a branch of mathematics, the term order is used in two unrelated senses:

<span><span>The order of a group is its cardinality, i.e., the number of elements in its set. Also, the order, sometimes period, of an element a of a group is the smallest positive integer m such that <span>am = e</span> (where e denotes the identity element of the group, and am denotes the product of m copies of a). If no such m exists, a is said to have infinite order.</span><span>The ordering relation of a partially or totally ordered group.</span></span>

This article is about the first sense of order.

The order of a group G is denoted by ord(G) or | G | and the order of an element a is denoted by ord(a) or | a |.

How many moles of CO2 are there in 8.91 x 1023 molecules of CO2?<br> (1 mole= 6.02 x 1023)
Karo-lina-s [1.5K]

Answer:

<h2>1.48 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{8.91 \times  {10}^{23} }{6.02 \times  {10}^{23} }  =  \frac{8.91}{6.02}  \\  = 1.480066...

We have the final answer as

<h3>1.48 moles</h3>

Hope this helps you
