19. what is sthe mass of 6.02 x 1024 atoms
of magnesium? [mg = 24, avogad
con stant = 6.02 x 10 23 atoms mol-1
(a) 240g (b) 24g (c) 2.4g (d) 0.24

The mass of magnesium in atoms is 240 g.

Option A

Explanation:

First, we have to convert the atoms to moles of magnesium.

We know that atoms are present in 1 mole of magnesium. So,

Thus,

Thus, 240 g of Magnesium is present in atoms.

in chemistry, a solution’s concentration is how much of a dissolvable substance, known as a solute, is mixed with another substance, called the solvent. the standard formula is c = m/v, where c is the concentration, m is the mass of the solute dissolved, and v is the total volume

the answer is 1260

you spend 7 hours in school for 1 school day with 5 school days in 1 school week with 36 school weeks in a school year.

7*5*36= 1260 it's all about multiplying
