Answer:
to make sure the cholerie is not to high
Electrolytes are inorganic substances that dissociate into ions in water. Examples of electrolytes include salts [for example, sodium chloride (NaCl) and magnesium chloride (MgCl2)] and ions [for example, potassium (K+)].
a. 301 cg
b. 6.2 km
Explanation:
a. knowing that 1 gram (g) is equal to 100 centigrams (cg) we devise the following reasoning:
if 1 g is equal to 100 cg
then 3.01 g are equal to X cg
X = (3.01 × 100) / 1 = 301 cg
b. knowing that 1 kilometer (km) is equal to 1000 meters (m) we devise the following reasoning:
if 1 km is equal to 1000 m
then Y km are equal to 6200 m
Y = (6200 × 1) / 1000 = 6.2 km

Explanation:
Given that,
Mass number, A = 302
Atomic number, Z = 119
We know that, atomic number = no of protons
Protons = 119
Mass no. = No. of neutrons + No. of protons
302 = No. of neutrons + 119
No. of neutrons = 302 - 119
= 183
No. of electrons = No. of protons
= 119
