<span>35 grams
The average salinity of seawater is 35 parts per thousand, so multiply the mass of seawater provided by 0.035 and you'll get the amount of salt (mostly sodium chloride) dissolved in it. So
1000 g * 0.035 = 35 g
Therefore in 1 kilogram of seawater with average salinity, there is 35 grams of salt.</span>

Answer: 9.09 %
Explanation:
To calculate the percentage concentration by volume, we use the formula:
Volume of ethanol (solute) = 30 ml
Volume of water (solvent) = 300 ml
Volume of solution= volume of solute + volume of solution = 30+ 300 = 330 ml
Putting values in above equation, we get:
Hence, the volume percent of solution will be 9.09 %.
Answer:
The number of years it would take you to earn what Mike Trout will earn on his contract is 4,265
Explanation:
Mike Trout of the Los Angeles Angels has a contract worth $426,500,000
On the other side, you earn $100,000 per year.
To calculate the number of years it would take for you to earn what Mike Trout will earn from his contract, you must divide the amount Mike earned by the amount you earned during a year:
$426,500,000 ÷ $100,000 per year= 4,265
The number of years it would take you to earn what Mike Trout will earn on his contract is 4,265
