tangare [24]
The best answer here is B , i.e. the components of a homogenous mixture are evenly distributed This means the constituents are mixed uniformly. In a heterogeneous mixture, the constituents are not mixed uniformly. Some good examples of a homogeneous mixture are: 1. Sugar solution 2. Soda 3. Water 5. soft drinks 6. Air 7. Vinegar 8. Brine Some examples of a heterogeneous mixture are: 1. Blood 2. Milk 3.Water and oil 4. Water and sand 5. Soil 6. Hollandaise sauce 8. smog

Calculate each of the following quantities:<br> (b) Amount (mol) of O atoms in 8.18 g of Ba(NO₃)₂
postnew [5]

The number of moles of O atoms in 8.18 g of Ba(NO₃)₂ is 0.364 mol.

<h3>What is moles?</h3>

"The mole is a SI unit of measurement that is used to calculate the quantity of any substance." It is denoted by mol.

Given that the mass of Ba(NO₃)₂ is  8.18 g

n = m/M

n = moles = ? mol Ba(NO₃)₂

m = mass(g) =  8.18 gram(NO3)2

The molar mass of Ba(NO₃)₂ is  261. 35g/mol.

As given, the moles of oxygen atom in Ba(NO₃)₂ is 6.

So, the moles of oxygen in 8.18 gram will be

Putting the value in the formula:

0.0607 mol Mg(NO3)2 × 6 mol O atoms/mol Mg(NO3)2 = 0.364 mol O atoms to three significant figures.

Thus, the number of moles of O atoms is 0.364 mol.
