To get the number of gold atoms, you have to divide the mass of the gold by the mass of the gold atom. It follows this simple equation
.
Let x be the number of gold atoms. Plug in the values to a calculator.
x =
Both have the same units so the unit gram(g) can be cancelled.
x then would be equal to 1.53x10^22. So there are 1.53x10^22 atoms of gold in 5 g of gold
Answer:
The cow digestive system is not at all like the human digestive system. The main difference between the human digestive system and the cow's animal digestive system is simple: Cows have a stomach that consists of four compartments, commonly referred to as four stomachs. Cows spend the better part of the day eating, swallowing and regurgitating their food, and chewing it again before final digestion. Because a cow's teeth mostly grind their food, cows use their tongues – which is why they are so long – to help them gather and grasp grass for pinching off between their incisors and dental pad at the front part of their mouths.

⇒ 
So that option E is the right answer.
Hello!
The pressure of the Ideal Gas when the volume is 1,45 L and the temperature is 298 K is
1,82 atm.
To solve this problem we need to apply the
Ideal Gas Law for the initial conditions and the final ones, clearing the equation for the number of moles (n) and the ideal gas constant (R) which remain constant:
Now we match n*R for the initial conditions (1) and the final ones (2), clearing the equation for P₂
Have a nice day!
