Question

The ratio by mass of the lightest element to that of metal present in the chemical formula of baking powder is

Answer 1

Answer:

Explanation:

The lightest element present is Hydrogen (₁²H).

Atomic mass of hydrogen = 1 amu

Or Molar mass of hydrogen = 1 g

The chemical formula of baking powder = NaHCO₃+ tartaric acid

Metal present is baking powder is sodium (₁₁²³Na)

Atomic mass of Sodium = 23 amu

Or molar mass of sodium = 23 g

Required ratio = mass of hydrogen/mass of sodium

                        = 1/23

Answer 2

Answer:

1/23

Explanation:

The lightest element known is Hydrogen.

Molar mass of hydrogen = 1g

Baking soda has a chemical formula of NaHCO₃

Molar mass of metal in NaHCO₃ = 23g (sodium)

Therefor, the ratio = (1/23)
