How do I calculate Molar Mass

ipn [44]

Answer:

Explanation:

The molar mass is the mass of a given chemical element or chemical compound (g) divided by the amount of substance (mol).

The molar mass of a compound can be calculated by adding the standard atomic masses (in g/mol) of the constituent atoms. hope this helps...

typical seawarer contains 2.7g of salt (sodium chloride,Nacl)per 100ml (100*10-3L).what is the molarity of Nacl in the ocean?

faust18 [17]

Answer:

Molarity = 0.5 M

Explanation:

Given data:

Mass of NaCl = 2.7 g

Volume = 100 mL(100×10⁻³L)

Molarity of solution = ?

Solution:

Formula:

Molarity = number of moles / volume in litter

Number of moles:

Number of moles = mass/ molar mass

Number of moles = 2.7 g/ 58.5 g/mol

Number of moles = 0.05 mol

Molarity = number of moles / volume in litte

Molarity = 0.05 mol / 100×10⁻³L

Molarity = 0.5 M

100 points! Formation of an Ion

RUDIKE [14]

$\huge\bold {Answer}$

Aluminum ions have a charge of +3. This means that the atoms have three more protons than electrons. In order to add electrons to aluminum ions, the purification process therefore requires a large amount of electricity.

Uncharged Aluminum atom must need to lose it's electrons,in order to form the bond with oxygen which has vacant orbitals

ion
atom that has a positive or negative charge because it lost or gained one or more electrons

chemical bond
the attractive force that holds atoms or ions together

ionic bond
a chemical bond in which one atom loses an electron and the other atom gains electrons to form ions

chemical formula
a combination of chemical symbols and numbers to represent a substance

covalent bond
bond formed by the sharing of electrons between atoms
