The net upward force that a fluid exerts on an immersed object. The ratio of force to the area over which that force is distributed. More pressure the deeper you go
pH can be defined as negative logarithm of hydronium ion concentration .
pH can be mathematical represented as :
pH =-log [H+]
[H+]=2.3*10^-9
pH= -log[2.3*10^-9]
=8.64
<span>The reasons to use insoluble salts to soften water would be to make the water more potable, and to enable better sudsing when washing clothes, dishes, or for taking showers.
Hard water tends to decay pipes at a faster rate, leave deposits on sinks, tubs, and toilets.
Hard water has a high percentage of calcium and other minerals that have an unpleasant taste and will often cause the joints between pipes to start leaking much much sooner than they would otherwise.</span>
I'm assuming that you want to covert atmospheres into mmHg.
mmHg is exactly like torr: there are 760 of them in an atmosphere.
The conversion would be 760 mmHg = 1 atm
Knowing this, simply multiply 2.48 * 10^3 by 760:
2.48 * 10^3 * 760 = 1,884,800 mmHg.
But wait! I'm assuming you probably meant to write 2.48 * 10^-3, since 1,884,800 is an awfully big number.
In that case:
2.48 * 10^-3 * 760 = 1.8848 mmHg
