Plz ! the picture below shows the weather station model at a particular location. which of these statements best describes the future weather condition at the location? there is 70 percent probability of rain showers. the temperature is most likely to be 64°f. there is 78 percent probability of thundershowers. the wind speed is most likely to be 64 knots.

Option (A)

Explanation: In the given figure, we observe that the wind direction is from the east to west and having a speed of about 5 knots which can be considered to be calm.

          The temperature is 78° and dew point is 64 and it has about 70% of chances of rain shower.

Note- Weather station model must be referred in order to understand what the numbers and the symbols depicts.

the grams   of   barium that   are in   2.3 x 10^23   atoms of barium   is   52.4 g (answer c)

    calculation

mass = moles   of ba   x molar   mass of ba

  molar mass of ba from periodic table=   137.3 g/mol

  use the   avogadro's law   constant   to   calculate the moles of barium

  that   is     1 mole =   6.02   x 10^23 atoms

                    ? moles = 2.3 x 10^23   atoms

by cross   multiplication

=(1 mole   x 2.3x 10^23 atoms)   / 6.02   x10^23 atoms)=   0.382   moles

mass   is therefore = 137.3   g/mol x 0.382 mol = 52.4 ( answer c)
