Answer:

a model from which later versions are developed

Explanation:

When we refer to something as a prototype, it simply means that that thing is a model product based on which many more of its kind can be made.

When trying to design a new product, prototypes are often made and tested. If they pass all the required quality tests, more products can now be designed based on the original product.

What is the mass of phosphorus that contains twice the number of atoms found in 14
yulyashka [42]

Answer:

15.5 gm

Explanation:

What is the mass of phosphorus that contains twice the number of atoms found in 14 g of iron?

[Relative atomic mass : P = 31; Fe = 56]

14 gm Fe = 14gm/ 56 gm/mole = 14 mole gm/56gm = 14/56 mole

0.25 moles

2 X 0.25 = 0.5 moles

1 mole P = 31 gm

so

0.5 moles P =31/2 =15.5 gm
