A 4-g mass of NaOH is dissolved in 5mL of water.
lapo4ka [179]
Molar mass NaOH = 40.0 g/mol

Volume in liters of solution :

5 mL / 1000 => 0.005 L 

number  of moles :

4 / 40 => 0.1 moles

M = n / V

M = 0.1 / 0.005

 = 20 mol/L or 20 M

hope this helps!

You will analyze four substances in this lab. Based on their chemical formulas and what you already know about covalent and ioni
Phoenix [80]

Answer: Oil: covalent

Cornstarch: Covalent

Sodium chloride: Ionic

Sodium bicarbonate: Ionic

Explanation: Covalent compounds are formed by sharing of electrons between non metals whereas ionic compounds are formed by transfer of electrons from metals to non metals.

1. Oil, which is built from the nonmetals hydrogen, carbon, and oxygen: forms a covalent compound by sharing of electrons between non metals hydrogen, carbon, and oxygen. Covalent compounds are insoluble in water.

2. Cornstarch, a carbohydrate consisting of hydrogen, carbon, and oxygen: forms a covalent compound by sharing of electrons between non metals hydrogen, carbon, and oxygen. Covalent compounds are insoluble in water.

3. Sodium chloride (table salt), whose formula is NaCl is formed by transfer of electrons from sodium to chlorine.Ionic compounds are soluble in water.

4. Sodium bicarbonate, whose formula is NaHCO_3 is formed by transfer of electrons from sodium to HCO_3.Ionic compounds are soluble in water.
