If the radius of the sun is 7.01×105 km, what is the volume of the sun in cm3?

1 km * 1000 m / km * 100 cm / m = 10^5 cm / km

V = 4 / 3 pi R^3

V = 4 / 3 * pi * (7.01 * 10^5 * 10^5)^3 = 4 / 3 pi * 344 * (10^10)^3

V = 1.443^10^3 * 10^30 = 1.44 10^33cm^3

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
