i have a question about atoms. How would i find electrons when the atomic number is the number of protons and electrons?
andre [41]

The atomic number is the same as the amount of electrons and protons. For example:
Oxygens atomic number is 8 so the proton and electron count is 8.
Hydrogens atomic number is 1 so the proton and electron count is 1.

A gas is confined in a 0.3m diameter cylinder by a piston, on which rests a weight. The mass of the piston is 85 kg. The local a
iris [78.8K]

Explanation:

Force applied on the gas will be as follows.

                   F_{gas} = F_{atm} + (m + M) g

As,   F = pressure × area. Hence, calculate the forces as follows.

                  F_{gas} = pressure × area

                         = 1.4 \times 10^{5} Pa \times \pi \times (\frac{0.3}{2})^{2}

                          = 1.979 \times 10^{4} N

                  F_{atm} = pressure × area

                            = 1.0133 \times 10^{5} \times \pi \times (\frac{0.3}{2})^{2}

                            = 1.432 \times 10^{4} N

      F_{gas} - F_{atm} = 5.47 \times 10^{3} N

Substituting the calculated values into the above formula as follows.

                F_{gas} = F_{atm} + (m + M) g

              F_{gas} - F_{atm} = (m + M) g

              5.47 \times 10^{3} N = (m + 85) \times 9.8    

              5.47 \times 10^{3} N = 9.8m + 833

                               m = 472.76 kg

Thus, we can conclude that the mass is 472.76 kg.
