Answer:
<h2>1.23 moles</h2>
Explanation:
To find the number of moles in a substance given it's number of entities we use the formula
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
We have the final answer as
<h3>1.23 moles</h3>
Hope this helps you
Answer:
The mass of 16.3 moles of nickel is 956. 647 g.
Explanation:
Given data:
moles of nickel = 16.3 mol
molar mass of nickel = 58.69 g/mol
mass in gram = ?
solution:
Formula:
number of moles = mass / molar mass
mass = number of moles × molar mass
mass = 16.3 mol × 58.69 g/mol
mass= 956. 647 g
In this case, among the list of components given, the abiotic factors are water, rock, soil, and sun.
<h3>What is an abiotic factor?</h3>
An abiotic factor is a non-living part of an ecosystem that shapes its environment.
Biotic and abiotic factors make up a community via interaction.
Biotic factors are considered living things (having "life") while abiotic factors are simply non-living things.
Hence, in this case, among the list of components given, the abiotic factors are water, rock, soil, sun

Hello!
the atomic mass of one atom of hydrogen is equal to 1.00784 in atomic mass units
one atomic mass unit is equal to 3.6609e-27 pounds
which means one atom of hydrogen is equal to 3.9478732e-27 pounds
I hope this helps, and have a nice day!
The subscript is the amount of atoms in each molecule and the coefficient is the amount of molecules. there are 4 Hydrogen, 2 Sulfur, and 8 Oxygen in this particular substance.
