Explanation:

there is a garden in Rama's house in the middle of the garden there is a path.they dicided to tile of path using tile of path tiles of length 2feet,3feet,7feet.the Manson tiled the first row with 2feet tiles ,the second row with 3feet tiles and the third row 7feet tiles .the Manson has not cut any of the tiles.then what is the shortest length of path ?ಠ_ಠ

Answer 2

$\textbf{Answer:-}$

Concept:-

A mole is defined as the amount of substance containing the same number of discrete entities (atoms, molecules, ions, etc.)

$1 \: mol \: = 6.022 \times {10}^{23}$

Calculation:-

The molar mass of oxygen is 16 grams.

1-mole oxygen weighs 16 grams.

64 gram oxygen = 64/16 = 4 mole oxygen.

$1 \: mole \: of \: any \: element \: contains \: 6.022 \\ \times {10}^{23}atoms.$

$∴ no. \: of \: atoms \: in \: 4 \: mole \\ o_{2} = 4 \times 6.022 \times {10}^{23} = 24.088 \times {10}^{23}atoms.$

$So \: the \: no. \: of \: oxygen \: atoms \: in \: 64 \: grams \: of \: oxygen \: gas \: is \: 24.088 \times {10}^{23}≈24.092 \times {10}^{23}$
