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:
The answer to your question is the letter C. 2.906 x 10²³ atoms
Explanation:
Data
mass of Lead = 100 g
The Number of atoms = ?
Process
1.- Look for the atomic number of Lead in the periodic table
Atomic number = 207.2 g
2.- Use proportions and the Avogadro's number to calculate the number of atoms.
207.2 g ------------------ 6.023 x 10²³ atoms
100 g ----------------- x
x = (100 x 6.023 x 10²³) / 207.2
x = 6.025 x 10²⁵ / 207.2
x = 2.906 x 10²³ atoms
