how many atoms are in 95 grams of copper

Answers

Answer 1

Answer:

Here's a quick conversion before I answer your question, use it whenever needed.

1 moles Copper to grams = 63.546 grams. 2 moles Copper to grams = 127.092 grams. 3 moles Copper to grams = 190.638 grams. 4 moles Copper to grams = 254.184 grams. 5 moles Copper to grams = 317.73 grams. 6 moles Copper to grams = 381.276 grams. 7 moles Copper to grams = 444.822 grams.

Ok, now I'll answer your question.

Atomic masses are given in atomic mass units. One atomic mass unit is equal to one gram per mole. When you add these together for a compound, you get the molar mass of that compound. For example, silicon dioxide consists of one silicon atom and two oxygen atoms. The atomic mass of silicon is 28 grams and the atomic mass of oxygen is 16 grams.

(Hope the conversion and the answer helped) Sky

1.) How do plant scientists hope to improve plant processes?
2.) How could you find out which resources are the most important for a plant to grow?

Answers

Plant scientists long have known they can alter crops genetically to improve performance; they've been doing it thousands of years. ... "We changed the way the plant is expressing its genes, even though we didn't change the genes themselves," Mackenzie said. The process is called epigenetics

In particular, plants need nitrogen, phosphorus and potassium. When dissolved in water, these nutrients get absorbed by a plant's roots. If a plant can't get the nutrients it needs from the soil, fertilizer can help. Fertilizer provides plants with essential nutrients and helps them grow faster

HURRY PLEASE In Maglev trains, fields exist between objects that are not in contact but can interact at a distance.

Answers

the answer is true your welcome

In Maglev trains, magnetic force exist between objects that are not in contact but can interact at a distance.Hence, the statement is true.

What is a force?

Force is defined as a cause which is capable of changing the motion of an object. It can cause an object which has mass to change it's velocity. It is also simply a push or a pull . It has both magnitude as well as direction.Hence, it is a vector quantity.

It has SI units of Newton and is represented by'F'.Newton's second law states that force which acts on an object is equal to momentum which changes with time. If mass of object is constant, acceleration is directly proportional to net force acting on an object.

The concepts which related to force are thrust and torque .Thrust increases the velocity of an object and torque produces change in rotational speed of an object.
