Salinity has units of grams NaCl or salt per kilogram solution. We can use the density given and the molar mass of the salt to convert from salinity to molarity. We do as follows:
( 5.6 g / kg ) ( 1.03 kg / L ) ( 1 mol / 58.44 g ) = 0.0987 mol NaCl / L
Answer: A convex lens is used to converge ligtht.
Explanation:
A concave lens is a lens that is thicker on the ends than in the middle. As consequence of this, a concave lens diverges (separate) the rays of light. A concave lens is also called diverging lens.
A convex lens is is thicker in the middle than on the ends. As consequence of this, a convex lense converge the parallel rays that pass through it. A convex lens is also called converging lens.
It might be more suitable because some data cannot use a graph to show data because there is too much data.
The empirical formula will be CHCl
<h3>What is the empirical formula?</h3>
The simplest whole number ratio of atoms in a compound is the empirical formula of a chemical compound in chemistry. Sulfur monoxide's empirical formula, SO, and disulfur dioxide's empirical formula, S2O2, are two straightforward examples of this idea. As a result, both the sulfur and oxygen compounds sulfur monoxide and disulfur dioxide have the same empirical formula. They do not, however, have the same molecular formula, which specifies how many atoms are present in each molecule of a chemical compound.
For saran
C= 24.8% ,
H= 2.0% ,
Cl = 73.1%
= 24.8/ 12 = 2.0
= 2.0/1=2.0
= 73.1/ 35 = 2.0
Now, dividing each mole by the smallest moles (hydrogen's moles), one obtains:
C= 2.0 / 2.0 = 1
H= 2.0/2.0 = 1
Cl = 2.0/ 2.0 = 1
The empirical formula will be CHCl
