Chemistry
1 answer:
Zepler [3.9K]3 years ago
7 0

Answer:

<h3>The answer is 0.4 moles</h3>

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{2.4 \times  {10}^{23} }{6.02 \times  {10}^{23} }  =  \frac{2.4}{6.02}  \\  = 0.398671096....

We have the final answer as

<h3>0.4 moles</h3>

Hope this helps you

What are Intensive and Extensive properties?
lianna [129]
Intensive properties are the properties which values doesnt change with the amount of mass or material that you have, example density, melting point boiling point, molecular mass

Extensive are properties that depends of how much mass or material you have. Example: mass, number of moles, volume, pressure, number of students, population, 

mass, volume, quantity (there is only one of each), color, reflect light, temperature, energy

2.0 grams of ZnSO4 reacts completely with Li2CO3; how many grams of Li2SO4 would be produced?
grin007 [14]
Moles of ZnSO4 = Mass/Mr
= 2/(65.4 + 32.1 + (16 x 4))
= 0.012383.... mol

Since there is no chemical equation provided, I will assume that the ratio of ZnSO4:Li2CO3 is 1:1

Therefore there are 0.012383 mil of Li2SO4 as well
So the mass would be Moles x Mr = 0.012383.... x ((6.9 x 2) +32.1 + (4x16))
= 1.360 g of Li2SO4 produced
