V = nRT/P

substitute value of V and P

V =nRT/P

mass*density = nRT/P

density will not change

A solution contains 1500 mEq of potassium per Liter. How many mmols of potassium are contained in the Liter?
netineya [11]

Answer:

1500 mmol.

Explanation:

Hello,

In this case, for such monovalent potassium species, we can verify that 1 mEq equals 1 mmol, therefore, the required solution is shown below:

1500 mEq*\frac{1mmol}{1mEq} \\\\=1500 mmol

Which means that also 1500 mmol of monovalent potassium ions are contained in the liter.

Regards.

would the pressure exerted by the gas in the tank would increase if the scuba tank were to increase in temperature?
ludmilkaskok [199]

Answer:

In fact, a full scuba tank will gain about 5-6 psi for every degree of temperature increase. This is one reason that full tanks should not be left in a hot trunk of a car. A tank filled to 3000 psi could easily reach 3500 psi if the temperature of it increased substantially.
