The sun is mostly composed of the elements hydrogen (H) and helium (He). By mass the composition of the sun is 75 percent hydrogen and 25 percent helium. Various metals make up less than 0.1 percent of the mass of the sun. The temperature of the sun’s surface is about 10,340 degrees Fahrenheit (5,726 degrees Celsius).
I think the answer is (c)
Answer:
The total mass of water in on Earth's surface is
.
Explanation:
Total planetary surface area = T = 
Total land area of planet = L = 
Total water area of planet = W
T = L + W


Volume = Area × Depth
Volume of water on earth = V
V= 


Total mass of total water on the earth = M
Density of the water,D = 1 g/mL = 0.001 kg/0.001 L=1 kg/L
1 g - 0.001 kg
1 mL = 0.001 L



The total mass of water in on Earth's surface is
.
