Answer:

Number of grams of mineral salt in one liter of water

Explanation:

Salinity :

It is the concentration of dissolved salts .

Salinity means the saltiness or the dissolved salt component in the water body . It is defined as mass (in gram) of the dissolved matter in the water bodies .

salts found in ocean water are :

Salts of chlorides, sulfates , sodium , magnesium, potassium and calcium

For example : world's oceans salinity is 3.5% parts per thousand (g/L) . It means 3.5 g of salt is present in 1 L of seawater .

Note : Sodium chloride is major salt found in ocean . But it is not the only salt present (other salts are also found) . So D can't be the answer

Explain why it is important to assume that the rate of radioactive decay aka radioactivity will remain constant over time?

marusya05 [52]

Answer and Explanation:

It's very important to assume that the rate of radioactive decay will remain constant over time to make scientists' lives easier when calculating the ages of fossils, compounds, etc.

If the rate changes, it would be extremely challenging for people to figure out the relative ages of rock strata, fossils, or other substances with radioactive elements in them. This is a fundamental assumption in order to be able to use radioactive dating.

Hope this helps!

How many grams of carbon (C) would be present in carbon monoxide (CO) that contains 2.666 grams of oxygen (O)? For example if th

oee [108]

Given :

Mass of oxygen containing carbon monoxide (CO) is 2.666 gram .

To Find :

How many grams of carbon (C) would be present in carbon monoxide (CO) that contains 2.666 grams of oxygen (O) .

Solution :

By law of constant composition , a given chemical compound always contains its component elements in fixed ratio (by mass) and does not depend on its source and method of preparation.

So , volume of solution does not matter .

Moles of oxygen , $n=\dfrac{2.666}{16}=0.167\ mole$ .
