Answer:
32.25
Explanation:
8NH3 + 3Cl2 → 6NH4Cl + N2
NH3 = 17 g/mol
number of moles = 1
NH4Cl= 43 g/mol
number of moles = 3/4
mass= 43 × ¾ ≈ 32.25 g
Answer:
15000
Explanation:
1000 Meters in a kilo meter. So multiply 15 by a 1000.
Answer:- 4.36 kPa
Solution:- At constant volume, the pressure of the gas is directly proportional to the kelvin temperature.

Where the subscripts 1 and 2 are representing initial and final quantities.
From given data:
= 1.049 kPa
= ?
= 7.39 K
= 30.70 K
For final pressure, the equation could also be rearranged as:

Let's plug in the values in it:

= 4.36 kPa
So, the new pressure of the gas is 4.36 kPa.
