Answer is 3.306 Pa.
<em>Explanation:</em>
This is a simple unit conversion problem.
1 atm = 760 mmHg = 101325 Pa
Hence,
0.0248 mmHg = (101325 Pa / 760 mmHg) x 0.0248 mmHg
= 3.306 Pa
Pressure can be measured by using many units such as atm, Pa, torr, bar, cmHg, mmHg and so on.
The relationships among those units as follows
1 atm = 101325 Pa = 1.01325 bar = 760 torr, 760 mmHg = 76 cmHg
Answer:
The energy of the products is less than the energy of the reactants, so energy is released into the surrounding environment.
The mass will stay the same because of the conservation of mass
Answer: 123 g
Explanation: Q =It = nzF. For Ca^2+ z= 2, t = 5.5 x 3600 s and I = 30.0
And F= 96485 As/mol
Amount of moles is n = It /zF = 3.078 mol , multiply with atomic mass 40.08 g/mol
