Calculate the number of moles in 32.5 g of Mg(NO3)2.

n = 0.219 moles

Explanation:

Given mass, m = 32.5 g

Molar mass of Mg(NO₃)₂ is :

M = 1 × 24 + 2× 14 + 6 × 16

M = 148 g/mol

Let there are n number of moles. It is equal to given mass divided by molar mass.

Hence, there are 0.219 moles in 32.5 g of Mg(NO₃)₂.

african americans demonstrated their newly found freedom by relocating often in search of relatives whom they had been separated from during slavery. others established schools to educate freed people and they built institutions such as churches and political organizations to advocate for their rights.

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
