What is the final volume of NaOH solution prepared from 100.0 mL of 0.500 M NaOH if you wanted the final concentration to be 0.1
suter [353]

Answer:

The final volume of NaOH solution is 30ml

Explanation:

We all know that

              V1S1 = V2S2

             or V1= V2S2÷S1

             or  V1= V2×S2×1/S1

             or   V1=100×0.15×1/0.50

                    V1= 30

∴30 ml NaOH solution is required to prepare 0.15 M from 100ml 0.50 M NaOH solution.

A scuba tank has a pressure of 195 KPa at a temperature of 10 °C. The volume of the tank is 350 L. How many grams of air is in t
marissa [1.9K]

The mass of air in the scuba tank is 841.614 g.

Using the ideal gas equation;

PV=nRT

P = pressure of the gas = 195 kPa

V = volume of the gas =  350 L

n = Number of moles of the gas = ??

R = molar gas constant = R = 8.314 J K-1 mol-1

T = temperature of the gas =  10 °C or 283 K

n = PV/RT

n = 195 * 350/8.314 * 283

n = 68250/2352.862

n = 29.00 moles

Number of moles = mass/molar mass

mass of air = Number of moles * molar mass

mass of air = 29.00 moles * 29g/mol

Mass of air = 841.614 g
