V=50 (л)

n=V/Vm, где Vm- объем газа при н.у. = 22.4 (л/моль)
n=50/22.4=2.23 (моль)
m=n*M
M(O3)=3*16=48 (г/моль)
m=2.23*48=107.04 (г)
N=n*Na, где Na - число Авагадро = 6.02*10^23 (г/моль)
N=2.23*6.02*10^23=13.43*10^23 (молекул)

Town or countryside

My name is Peter. I live in the countryside, in a cottage which is over 100 years old. The cottage is near a small village. I love living here because it's calm. There aren't many cars or busses, the streets are clean. You can go for a walk because there isn't any violence. You can even leave your doors open, nobody will steal anything.

We know all the neighbors and at the end of the day, people get together at the main square and chat. We go to bed early, as there isn't much to do in the evening. There isn't any disco, theater or cinema. We also don't have a museum or a youth club. But the children can play in the streets or in the fields and they can have animals.

You can sleep very well because there is no noise. You can hear the birds singing or the rain pouring. The air is pure and cool and you can see millions of stars.

It is a bit difficult in winter. Sometimes it snows a lot and then we are isolated for a few days. But still, I like living in the countryside.

My name is Ken. I live in a big town and I love it. Of course, there are lots of cars and buses, bikes and motorbikes, people trying to cross the streets. Traffic jams are normal and the air is bad. But there are lots of advantages too. There are more workplaces in the city, better schools, nicer shops, finer restaurants and bars, hundreds of cinemas and theaters, art galleries and museums. If you want to go for a walk, you can go to one of the parks. Of course, children can't play in the streets, but there are lots of youth clubs and amusement parks where children can enjoy themselves.
