Answer:

from formula,

n = <u>speed</u><u> </u><u>of</u><u> </u><u>light</u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u>

speed of light in medium

In Silica,

1.44 = (3e8m/s)/v

v= (3e8m/s)/1.44

v = 20.83e7m/s

v = 20.8 × 10^7m/s.

Light travels in silica at 20.8 × 10^7 m/s.

Answer:

2.08 x 108 m/s

The speed of light in this fiber is found to be v = c/n = (3.00 x 108 m/s)/(1.44) = 2.08 x 108 m/s.

The 54.9-g sample of the compound X2O7 contains 33.6 g of oxygen atoms. What is the molar mass of element X?
vazorg [7]
Mass of X₂O₇ = 54,9g

2x + 33,6g = 54,9g
2x = 54,9g - 33,6g
2x = 21,3g  | :2
x = 10,65g/mol
