Calculate the density of oxygen,

Chemistry
1 answer:
abruzzese [7]3 years ago
5 0

Answer:

density of oxygen = 1.307 g/l

Explanation:

given pressure = 1 atm temperature = 298 k

PM=DRT

where p is pressure M is molecular mass D is density R is gas constant and T is temperature

substituting the values in the equation

1\times 32=D\times 0.0821\times 298

D = 1.307 g/l.

Calculate the density of a solid in g/cm3 if it weighs 38.3 kg and has a volume of 0.00463 m3.
RideAnS [48]

Answer: D=8.27 g/cm³

Explanation:

Density is mass/volume. Mass is in grams and volume is in liters. In this case, the problem wants our volume to be in cm³. All we need to do is to make some conversions to convert kg/m³ to g/cm³.

D=\frac{38.3kg}{0.00463m^3} *\frac{(1m)^3}{(100cm)^3} *\frac{1000g}{1kg}

With this equation, the m³ and kg cancel out, and we are left with g/cm³.

D=8.27 g/cm³

Estimate the pH of the resulting solution if you mixed equal amounts of hydrochloric acid (HCI) and sodium hydroxide (NaOH).
ioda
It obtains a neutral pH (7). The combination of a strong acid and a strong base results in a neutral pH. The pH of HCl is about 1, and the pH of NaOH is 14.

Chlorine is the most widely used disinfectant for killing pathogens during water treatment. Determine the kilograms of chlorine
makkiz [27]

Explanation:

The given data is as follows.

    Flow of chlorine (Q) = 10,000 m^{3}/day

Amount of liter present per day is as follows.

                  10,000 \times 10^{3} l/day

It is given that dosage of chlorine will be as follows.

                   10 mg/l = 10 \times 10^{-6} kg/l

Therefore, total chlorine requirement is as follows.

          Total chlorine requirement = (10,000 \times 10^{3}) \times (10 \times 10^{-6}) kg/day

                                        = 100 kg/day

Thus, we can conclude that the kilograms of chlorine used daily at the given water treatment plant is 100 kg/day.
