Answer:

107.3g

Explanation:Density = Mass/Volume

There are two methods either by taking the above formula and inserting the values or by using Mass = Denstiy*Volume

Here I have showed you both the ways:

1st

As Desnity  is 21.46g/cm^3

Volume = 5cm^3

Let m be mass

21.46g/cm^3=m/5cm^3

Cross multiplication takes place here

21.46*5=m

107.3 =m

Therefore, mass of platinum = 107.3g

2nd

Mass = Denstiy*Volume

Density = 21.46g/cm^3

Volume = 5cm^3

m=21.46g/cm^3* 5g/cm^3

m= 107.3g

5- Why do we only see one side of the moon?
prisoha [69]

Answer:

One side of the moon always faces the earth, which is called synchronous rotation. In other words, the length of time the moon rotates or revolves around its axis is the same as the length of time it takes to orbit the earth... Therefore, our moon always has a side facing the earth, which we call the near side of the moon.

Why do winter and summer climates vary more widely in much of eastern Europe?
Zarrin [17]
Due to two factors..
The first factor is the placement of Europe in relation to latitude lines.
Up north is bound to be more cold than most places down south near the Mediterranean sea. (Which is closer to the equator)
The second factor is the physical geography of the region. Ranging from mountain ranges like the Alps and the Urals to the flat planes of much of mid Europe. The weather interacts with these regions and determines the climates making up much of the continent. (Only takes a rudimentary understanding of basic earth science and geography to understand that. If you have more questions pertaining to the subject, pm me.)
