How many grams of mg are there in a sample of mg that contains 6.61×1023 atoms?

The answer to your question is: 26.7 g of Mg

Explanation:

Data

Mg = ? g

Mg = 6.61 x 10²³ atoms

Atomic mass Mg = 24.3 g

Rule of three

                              24.3 g of Mg  6.023 x 10²³ atoms

                                x                     6.61 x 10²³ atoms

                                x = (6.61 x 10²³  x   24.3) / 6.023 x 10²³

                                x = 26.7 g of Mg

i'm hoping this is like a multiple answer question. if it is then it would be, the location of the plants and also the height of the plants since one she wants to know where in her garden the chamomile grows best. but also to see which plants grew better in the location she also has to measure the plant itself. (if you can only choose one answer than it would be c).

i do not get it   at all
