The total volume of seawater is 1.5 x 1021l .assume that seawater contains 3.1 percent sodium chloride by mass and that its density is 1.03 g/ml .calculate the total mass of sodium chloride in kilograms and in tons (1ton =2000lb; 1lb =453.6 g).

Mass in kg = 4.7*10^19 kg

Mass in tons = 5.2*10^16 tons

Explanation:

Given:

Total volume of sea water = 1.5*10^21 L

Mass % NaCl in seawater = 3.1%

Density of seawater = 1.03 g/ml

To determine:

Total mass of NaCl in kg and in tons

Calculation:

Unit conversion:

1 L = 1000 ml

The volume of seawater in ml is:

To convert mass from g to Kg:

1000 g = 1 kg

To convert mass from g to tons:

1 ton = 9.072*10^6 g
