Suppose you have avogadro\'s number of mini marshmallows and use them to cover the state of california which has a land area of 1.560 × 105 mi2. each mini marshmallow has a diameter of 0.635 cm and a height of 2.54 cm. assuming the marshmallows are packed together so there is no space between them, to what height above the surface, in kilometers, will the mini marshmallows extend

The height that avogadro's number of mini marshmallows covering the land area of California will extend is 1199.6 km above the surface.

The Avogadro number is a constant which gives the number of elementary particles present in 1 mole of a substance.

The value of the Avogadro number is 6.02 × 10^23

Avogadro number of mini marshmallows = 6.02 ×10^23 mini marshmallows.

Assuming each marshmallow is a small cylinder, then the area of its circular base is:

Area circular base = π*r²

Area circular base = π * (0.635/2)²

Area circular base = 0.317 cm²

6.02 × 10^23 marshmallows will cover an area of 6.02 × 10^23 * 0.317 cm² 

Area covered = 1.908 × 10^23 cm² = 1.908 × 10^13 km²

The land area of california is  1.560 × 10^5 mi² = 4.04 × 10^5 km²

The number of times the 6.02 × 10^23 marshmallows will cover the land area of California is obtained by division:

Number of times = 1.908 × 10^13 km² / 4.04 × 10^5 km² =  4.7227 ×10^7 times

To obtain the height of the mini marshmallows, the height of a mini marshmallow is multiplied by the number of times the mini marshmallows will cover the land area of California.

Height = 4.7227 × 10^6 * 2.54 cm

Height = 1.1996 ×10^6 cm

Height in kilometres = 1199.6 km above the surface

Therefore, the height of avogadro's number of mini marshmallows covering the land area of California is 1199.6 km above the surface.
