Answer:
3.37kg of NaCl is the salt content of the dead sea
Explanation:
A concentration of 33.7% means there are 33.7g of NaCl in 100mL of solution.
To solve this question we need to convert 10.0L to mililiters, and then, solve for the mass of NaCl in grams and convert it to kg:
<em>Volume in milliliters:</em>
10.0L * (1000mL / 1L) = 10000mL
<em>Mass of NaCl:</em>
10000mL * (33.7g NaCl / 100mL) = 3370g NaCl
<em>In kg:</em>
3370g * (1kg / 1000g) =
<h3>3.37kg of NaCl is the salt content of the dead sea</h3>
Petroleum, also called crude oil, is a fossil fuel. Like coal and natural gas, petroleum was formed from the remains of ancient marine organisms.
<h3>
What are the uses of crude oil?</h3>
We use petroleum products to run our vehicle like car, bikes, boats, aeroplanes and many more other things. In the industrial sector, the petrochemical industry uses petroleum as a raw material (a feedstock) to make products such as plastics, polyurethane, solvents, and hundreds of other intermediate and end-user goods.
1. It is used for Food Production
2. It is used for Transportation
3. It is used in Clothing Materials
4. It is used as Products in our Home
5. From the Crude Oil we can extract the oil, petrol, jet fuel and many other things
So we can conclude that: Petroleum, also called crude oil, is a fossil fuel. Like coal and natural gas, petroleum was formed from the remains of ancient marine organisms.
