2Na + 2H₂O = 2NaOH + H₂↑ 

M(Na) = 23 г/моль
M(NaOH) = 23 + 16 + 1 = 40 г/моль
m(NaOH) = (124 г * 40 г/моль * 2 моль) : (23 г/моль * 2 моль) = 215,65 г

Reading Task 1. Read the story.
Hi! My name’s Laura. I’m 14 years old. I live in a big city in Kazakhstan Pavlodar. I think life in a big city is fantastic. I like going to the theatre or cinema and visiting museums. I love pop music and there are usually pop concerts in the city. We go to the concerts with my friends.
One thing I don’t like about the city is the traffic. There are always lots of cars and buses in Pavlodar and they make a lot of noise.
My best friend Azamat lives in a small village near Pavlodar. Azamat thinks life in the countryside is very nice. There’s no traffic. People can work outdoors.
It is calm, silent and peaceful in the countryside. There’s more oxygen in the air because there are a lot of trees around. You can see wonderful flowers everywhere. There is a beautiful lake and a wonderful forest near his village. He usually goes rowing in the lake.
We like walking in the forest or swimming in the lake.
