The elements in each group have the same number of electrons in the outer orbital<span>. Those </span>outer<span> electrons are also called valence electrons. They are the electrons involved in chemical bonds with other elements. Every element in the first column (group one) has one electron in its </span>outer<span> shell.</span>

The mass of titanium is = 47,867 g/1mol
Applying the rule of avrogado
1mol _______ 6,023 × 10^(23) at
0,075mol ___ x
X . 1mol = 0,075mol . 6,023 . 10^(23)at
X = 0,075 . 6,023 . 10^(23) at
X = 4,51 . 10^(22) atoms
Hope this helps
Answer:
1 tablet
Explanation:
Assuming that gm stands for gram:
Put everything in one unit, 0.3 g = 300 mg.
And given that each tablet is 300 mg:
mass/amount = 300mg / 1 tablet
300mg / X amount = 300mg / 1 tablet
(300mg/300mg) tablet = X = 1 tablet
So it is 1 tablet you need.
