the atomic mass of tungsten is 183.84 grams
this is the mass of one mole of tungsten we know that one mole of any substance contains Avagadro number of atoms or molecules or ions.
So one mole of tungsten metal will have 6.023 X 10^23 atoms
thus mass of 6.023 X 10^23 atoms is 183.84 grams hence mass of single atom = 183.84/ 6.023 X 10^23 atoms
= 30.52 X10^-23 = 3.052 X 10^-22 g
It's sodium chloride.
sodium chloride is table salt which is a pure substance. it's a compound but not a mixture.
note that iodized salt is a mixture, but we're just talking sodium chloride here.
Answer:
470.4N
Explanation:
Given parameters:
Mass of Stephanie = 48kg
Unknown:
Force she exerts while falling to the ground = ?
Solution:
The force she exerts is her weight;
Weight = mass x acceleration due to gravity
Now insert the parameters ands solve ;
Weight = 48 x 9.8 = 470.4N
Answer:
I'm going to call the length of the bracelet the number of times you have to add to get back to the first bead. This is the same as the number of beads, except in one case:
The shortest bracelet has length 1 and starts with (0,0). If you add one time, you get back to the first 0. But the bracelet has two beads. (Every bracelet has to have at least two beads to start.) The next shortest bracelet starts with (0,5), and has length 3: 0 5 5.
There is a bracelet of length 4 that starts with (2,6) (the first example on the main page):
2 6 8 4
There is a bracelet of length 12 that starts with (1,3) (the second example on the main page):
1 3 4 7 1 8 9 7 6 3 9 2
There is a bracelet of length 20 that starts with (0,4)
0 4 4 8 2 0 2 2 4 6 0 6 6 2 8 0 8 8 6 4
There is a bracelet of length 60 that starts with (0,1)
Answer:
Thermal energy (also called heat energy) is produced when a rise in temperature causes atoms and molecules to move faster and collide with each other. The energy that comes from the temperature of the heated substance is called thermal energy.
