Answer:
[tex]V = 1.4\times 10^{18}\,m^{3}[/tex],[tex]m = 1.435\times 10^{21}\,kg[/tex]
Explanation:
The volume of all oceans is:
[tex]V = (1.4\times 10^{9}\,km^{3})\cdot (\frac{1\times 10^{9}\,m^{3}}{1\,km^{3}} )[/tex]
[tex]V = 1.4\times 10^{18}\,m^{3}[/tex]
Ocean water has a density of [tex]1025\,\frac{kg}{m^{3}}[/tex], the mass of all oceans is:
[tex]m = (1025\,\frac{kg}{m^{3}} )\cdot (1.4\times 10^{18}\,m^{3})[/tex]
[tex]m = 1.435\times 10^{21}\,kg[/tex]
Answer:
Explanation:
Volume of ocean = 1.4×10^9 km3
To m^3,
1.4 × 10^9 km^3 × (1000 m)^3/(1 km)^3
= 1.4 × 10^18 m^3.
Density of water = 1000 kg/m3
Mass = density × volume
= 1000 × 1.4 × 10^18
= 1.4 × 10^21 kg.
