How many grams of NaCl are needed to make 0.800 liter of a 5.00 M solution?
ziro4ka [17]

Answer:

             0.324 g is required to make 5.00 M solution of NaCl in 0.800 L.

Given data:

                 Molarity = 5.00 M

                 Formula Mass = 58.5 g/mol

                 Required volume = 0.800 L

To Find;

               Mass in gram = ?

Solution:

              Formula for calculating mass in gram is given as,

              Mass in gram = Molarity × Formula mass × Volume required / 1000 putting values

              Mass in gram = 5.00 M × 58.5 g/mol × 0.800 L / 1000

               Mass in gram = 0.234 g

the average kinetic energy of the particles in a gas increases as the temperature of the gas increases. explain​
sveticcg [70]

Answer:

Explanation: Volume versus Temperature: Raising the temperature of a gas increases the average kinetic energy and therefore the rms speed (and the average speed) of the gas molecules. Hence as the temperature increases, the molecules collide with the walls of their containers more frequently and with greater force.

Concerning Boyle's Law, if you had a gas at a pressure of 101 kPa and decreased the volume of the container holding the gas to o
Viefleur [7K]

Answer:

P_2=404 kPa

Explanation:

Hello,

In this case, the Boyle's is mathematically defined via:

P_1V_1=P_2V_2

Which stands for an inversely proportional relationship between volume and pressure, it means the higher the volume the lower the pressure and vice versa. In such a way, since the volume is decreased to one quarter, we can write:

V_2=\frac{1}{4} V_1

We can compute the new pressure:

P_2=\frac{P_1V_1}{V_2} =\frac{P_1V_1}{\frac{1}{4} V_1} =\frac{101kPa*V_1}{\frac{1}{4} V_1} \\\\P_2=4*101kPa\\\\\\P_2=404 kPa

Which means the pressure is increased by a factor of four.

Regards.

Is gastric (stomach) fluid an acid or a base?
Vitek1552 [10]

Answer: the such thing that we call gastric acid, is made/produced by the cells that srebwithi any lining of our stomac, they are coupled in places like feedback system that extend to the acid production when it is needed.

other cells that are within our stomach will bicarbonat, at the base to buffer the fluid making sure that it doesn’t become too acidic

so yes it is
