Sodium hydroxide is an alkali (a chemical compound that neutralizes or effervesces with acids and turns litmus blue; typically, a caustic or corrosive substance of this kind such as lime or soda.) which is also known as caustic soda. Caustic means "burning" and caustic soda takes its name from the way it can burn the skin. It has the chemical formula of NaOH. ... As a solid, the alkali is deliquescent and readily absorbs moisture and carbon dioxide from the air.
Answer:
Water forms the basis of almost every type of cosmetic product, including creams, lotions, makeup, deodorants, shampoos and conditioners. Water plays an important part in the process, often acting as a solvent to dissolve other ingredients and forming emulsions for consistency.
Explanation:
Answer: 120g/mol
Explanation:
Molar mass of 1 mole of CH3COOH is ( 12 +( 1 x 3) + 12 +16 + 16 + 1) = 60g/mol.
Therefore; Molar mass of 2 moles would be; 60 x 2 = 120g/mol.
The density of He is 1.79 x 10⁻⁴ g/mL
In other words in 1 mL there's 1.79 x 10⁻⁴ g of He.
To fill a volume of 6.3 L the mass of He required
= 1.79 x 10⁻⁴ g/mL * 6300 mL
= 11 277 * 10⁻⁴ g
Therefore mass of He required = 1.1277 g of He
