a term salinity refers to the amount of salt in water. the salinity of earths oceans is about 525 grams of dissolved salt for evert 15 kilograms of water. find the grams of salt for every gram of ocean water

Sagot :

Answer:

0.035 grams

Step-by-step explanation:

Grams of salt per gram of ocean water

  • Divide the amount of salt by amount of water
  • 525 g / 15 kg
  • 525 g / 15000 g [∴1 kg = 1000 g]
  • 0.035 / 1

For every gram of ocean water, there is 0.035 grams of salt dissolved in it.

The salinity of earths oceans,

→ a = 525 g

Amount of water for the salinity,

→ b = 15 kg

→ b = 15 × 1000

→ [ b = 15000 g ]

Then find the grams of salt for every gram of ocean water,

→ a ÷ b

→ 525 ÷ 15000

→ 0.035 g

Hence, answer is 0.035 grams of salt.
