The atomic mass of N is 14.01 g/mol, and the atomic mass of H is 1.008 g/mol. What is the molecular mass of NH3?
MakcuM [25]

Answer:

Option A = 17.03 g/mol

Explanation:

Given data:

Atomic mass of nitrogen = 14.01 g/mol

Atomic mass of hydrogen = 1.008 g/mol

Molecular mass of NH₃ = ?

Solution:

Molecular mass of NH₃ = (14.01 g/mol × 1) + (1.008 g/mol × 3)

Molecular mass of NH₃ = 14.01 g/mol + 3.024 g/mol

Molecular mass of NH₃ =  17.03 g/mol

Ammonia consist of hydrogen and nitrogen both are nonmetals that's why ammonia is an covalent compound.

A sample contains 16. 75 g of the radioisotope U-236 and 50. 25 g of its daughter isotope, Th-232. How long did it take for deca
garri49 [273]

The time taken for the isotope to decay is 46 million years.

We'll begin by calculating the number of half-lives that has elapsed. This can be obtained as follow:

  • Original amount (N₀) = 50.25 g
  • Amount remaining (N) = 16.75
  • Number of half-lives (n) =?

2ⁿ = N₀ / N

2ⁿ = N₀ / N

2ⁿ = 50.25 / 16.75

2ⁿ = 3

Take the log of both side

Log 2ⁿ = 3

nLog 2 = Log 3

Divide both side by log 2

n = Log 3 / Log 2

n = 2

Finally, we shall determine the time.

  • Half-life (t½) = 23 million years
  • Number of half-lives (n) = 2
  • Time (t) =?

t = n × t½

t = 2  × 23

t = 46 million years
