Answer:
146.885 kPa
Explanation:
1 atm= 101.3 kPa =1.013 barr= 760 torr = 760 mmHg= 14.7 psi
So to convert atm to kpa we would multiply 1.45 by 101.3 which gives us 146.885.
1.45atm×
=146.885 kPa
Answer:
8 neutrons
A is the number of neutrons plus protons in the nucleus. However, we already know that there are 7 protons. Therefore, there must be 8 neutrons in the nucleus to add up to 15. Table 3.
Element Symbol Number of Neutrons
carbon 146C 8
nitrogen 147N 7
157N 8
oxygen 168O 8
Explanation:
Answer:
the mass of 8.03 mole of NH3 is 136.51 g
Explanation:
The computation of the mass is shown below:
As we know that
Mass = number of moles × molar mass
= 8.03 mol × 17 g/mol
= 136.51 g
Hence, the mass of 8.03 mole of NH3 is 136.51 g
We simply multiplied the number of moles with the molar mass so that the mass could come
The metal is 6 a 5.00 g piece of metal is heated to 100. Then places in a beaker containing 20.
