That 1 mole of Silicon weighs 28.0855 g. Therefore, 28.0855 g of Silicon contains 6.022×1023 of Silicon atoms. hope this helps :)
<span>The mass of an object is measured in either grams or kilograms. Mass is best described as the amount of matter, or "stuff," in a solid, and is different from weight (which is the force of gravity on an object). Since mass is used with solids, it will be measured in grams or kilograms (rather than in something like liters, which would be used with the volume of a liquid). To measure mass, you can use a balance, for example a triple balance beam.</span>
Yes thats true! You always have to think about the question or project before you start a science experiment! :)
Answer: B. Was twice as tall
Explanation: The strength of the gravitational force between two objects depends on two factors, mass and distance. If the distance is doubled, the force of gravity is one-fourth as strong as before.
