7 0

Answer:

8749.73× 10²³ atoms of He

Explanation:

Given data:

Number of atoms of neon = ?

Number of moles of neon = 1452.96 mol

Solution:

The given problem will solve by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.

The number 6.022 × 10²³ is called Avogadro number.

1 mole = 6.022 × 10²³ atoms

1452.96 mol ×  6.022 × 10²³ atoms of He/ 1 mol

8749.73× 10²³ atoms of He

NeX [460]

Answer:

212.996 or 213 approx.

hope it helps.

Molar mass of Al - 27

Molar mass of N - 14

Molar mass of O - 16

so, the molar mass of (No3)3 will be (14+16×3)3 which is equals to 186.

so, Molar mass of Al(No3)3 will be 186+27 = 213.

Which of the following describes the correct sequence of the movement of food during digestion?
Simora [160]


Mouth ⇒ oesophagus ⇒ Stomach ⇒ small intestine ⇒ large intestine ⇒ rectum ⇒ anus.

Note: the liver produces bile which neutralises the acidity of hydrochloric acid in the stomach, but food does not go through the liver. Moreover, the pancreas is a major part in enzyme production, but food does not pass through the pancreas either.
