The answer to this question would be: 3 molar
A molar unit will be equal to moles of solute per 1 liter of solvent. In this question, you are given the volume of the solution (264.8ml) and the weight of the molecule(139mg). Since the unit is moles not mg, then you need to convert the molecule into moles. To do that you need to know the ascorbic acid molecular weight which was: 6*12 + 8*1 + 6 *16 =<span>176mg/moles.
molecule in moles= 139mg/ (176 mg/moles)= 0.79 moles
Then the molarity of the juice should be: 0.79 moles/ (1000ml/264ml)= 2.991 M= 3 M</span>
Desalination is a process that takes away mineral components from saline water.

Explanation:
Both transition metals and alkali metals are good conductors of heat and electricity, react with water, and are easily oxidized.
<h3>What are alkali metals and transition metals?</h3>
The alkali metals are elements of group 1 which are lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs), and francium (Fr). They are also known as the s-block elements because they have their outermost electron in an s-orbital.
The alkali metals are shiny, soft, highly reactive metals and readily lose their outermost electron to create cations with charge +1. They can tarnish rapidly in the air due to oxidation by atmospheric moisture and oxygen.
Transition elements or transition metals are elements that have partially filled d-orbitals. An element having a d-subshell that is partially filled with electrons or can form stable cations with an incompletely filled d orbital.
Any element present in the d-block of the modern periodic table which consists of groups 3 to 12, is considered to be a transition element. For example, the mercury in the +2 oxidation state, corresponds to an electronic configuration of (n-1)d¹⁰. Many paramagnetic compounds are formed by transition metals because they have unpaired electrons in the d orbital.
