Fibre , it is a long thin strand or something like thread of material.
Fabric, it is a cloth material made by weaving or knitting threads together.
Answer:
They all wear their skeletons on the outside! This is called an exoskeleton and all creatures that have their structure on the outside are included in the phylum of Arthropods.
Explanation:
<u>Answer:</u> The initial molarity of cation is 2.38 M
<u>Explanation:</u>
To calculate the molarity of solution, we use the equation:
We are given:
Given mass of = 46.3 g
Molar mass of = 129.6 g/mol
Volume of solution = 150 mL
Putting values in above equation, we get:
1 mole of produces 1 mole of cation and 1 mole of anion
So, molarity of cation = (1 × 2.38) = 2.38 M
Hence, the initial molarity of cation is 2.38 M
Explanation:
As it is given that both the given containers are at same temperature and pressure, therefore they have the same density.
So, mass of in container- 1 is as follows.
5.35 mol x molar mass of
= 7.61 mol x 146.06 g/mol
= 1111.52 g
Therefore, density of will be calculated as follows.
Density =
density =
= 0.532 g/mL
Now, mass of in container- 2 is calculated as follows.
4.46 L x 1000 mL/L x 0.532 g/mL
= 2372.72 g
Hence, calculate the moles of moles present in container 2 as follows.
No. of moles =
=
= 16.24 mol
Since, 1 mol contains 6 moles F atoms
.
So, 16.24 mol contains following number of atoms.
=
= 97.46 mol
Thus, we can conclude that moles of F atoms in container 2 are 97.46 mol.
