If 1mol ------- is ----------- 6,02×10²³
so x     ------- is ----------- 1,39×10²⁴

x=\frac{1,39*10^{24}*1mol}{6,02*10^{23}}\approx2,31mol

Answer is: there are 2.308 moles of carbon.

N(C) = 1.39·10²⁴; number of carbon atoms.

n(C) = N(C) ÷ Na.

n(C) = 1.39·10²⁴ ÷ 6.022·10²³ 1/mol.

n(C) = 2.308 mol; amount of carbon atoms.

Na is Avogadro number or Avogadro constant (the number of particles, in this example carbon, that are contained in the amount of substance given by one mole).

Define climate and weather. What is climate change? Why is it important to know about climate change?
olga55 [171]

Answer:

It's important that we understand how the climate is changing so that we can prepare for the future. Studying the climate helps us predict how much rain the next winter might bring, or how far sea levels will rise due to warmer sea temperatures.

Weather is the state of the atmosphere at any given time and place.

Climate is the long-term average of the weather in a given place
