How many moles are in 3.0x10 to the 22 power atoms of magnesium

0.0498 moles

We are given;

We are required to calculate the number of moles of Magnesium;

Moles = 3.0 × 10^22 atoms ÷ 6.022 × 10^23 atoms/mol

          = 0.0498 moles

Hence, the number of moles in 3.0 × 10^22 atoms is 0.0498 moles

alfred von schlieffen, german army chief of staff, was given instructions to devise a strategy that would be able to counter a joint attack. in december, 1905, he began circulating what later became known as the schlieffen plan. schlieffen argued that if war took place it was vital that france was speedily defeated.

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
