About 6 × 109 g of gold is thought to be dissolved in the oceans of the world. If the total volume of the oceans is 1.5 × 1021 L

Lelechka [254]

First, determine the number of moles of gold.

Number of moles = $\frac{given mass in g}{molar mass}$

Given mass of gold = $6 \times 10^{9} g$

Molar mass of gold = 196.97 g/mol

Put the values,

Number of moles of gold = $\frac{6 \times 10^{9} g}{196.97 g/mol}$

= $0.03046\times 10^{9} mole$ or $3.046\times 10^{7} moles$

Now, molarity = $\frac{moles of solute}{volume of the solution in liters}$

Put the values, volume of ocean = $1.5 \times 10^{21} L$

Molarity = $\frac{3.046\times 10^{7} moles}{1.5 \times 10^{21} L}$

= $2.03\times 10^{-14} M$

Thus, average molar concentration = $2.03\times 10^{-14} M$

How to measure with SI UNIT

nordsb [41]

The SI base units and their physical quantities are the metre for measurement of length, the kilogram for mass, the second for time, the ampere for electric current, the kelvin for temperature, the candela for luminous intensity, and the mole for amount of substance.
