0.28gram of NH3 on decomposition gave 0.25gram of nitrogen and hydrogen. Find the volume of hydrogen evolved at Ntp. (2gram hydr
hodyreva [135]

The volume of H₂ evolved at NTP=0.336 L

<h3>Further explanation</h3>

Reaction

Decomposition of NH₃

2NH₃ ⇒ N₂ + 3H₂

conservation mass : mass reactants=mass product

0.28 NH₃= 0.25 N₂ + 0.03 H₂

2 g H₂ = 22.4 L

so for 0.03 g :

\tt \dfrac{0.03}{2}\times 22.4=0.336

Answer:

236 g/mol

Explanation:

This question is asking to calculate the molar mass/formula mass of calcium nitrate tetrahydrate with the chemical formula: Ca(NO3)2 · 4H20. This is done as follows:

Atomic mass of the constituent elements are as follows:

Ca = 40

N = 14

O = 16

H = 1

Hence, in Ca(NO3)2 · 4H20.

= 40 + {14 + 16(3)}2 + 4 {1(2) + 16}

= 40 + {14 + 48}2 + 4{2 + 16}

= 40 + {62}2 + 4{18}

= 40 + 124 + 72

= 236

Hence, the molar mass of Ca(NO3)2 · 4H20 is 236g/mol.
