Answer:- 3.68M.

Solution:- We have a 22.0% by mass solution of ethylene glycol and it's density is 1.04 gram per mL. It ask to calculate the molarity of the solution. We know that molarity is moles of solute per liter of solution. So, we need to figure out the moles of ethylene glycol and volume of solution.

Let's say we have 100 grams of the solution. Then mass of ethylene glycol would be 22.0 grams. Molar mass of ethylene glycol is 62.07 gram per mol.

Let's calculate it's moles first:

22.0gC_2H_6O_2(\frac{1mol}{62.07g})

= 0.354molC_2H_6O_2

From mass and density we calculate the volume of the solution and convert it to liters as:

100g(\frac{1mL}{1.04g})(\frac{1L}{1000mL})

= 0.0962 L

molarity=\frac{0.354mol}{0.0962L}

= 3.68M

So, the molarity of ethylene glycol solution is 3.68M.

When comparing Potassium (K) and Calcium (Ca) you must compare?
Rom4ik [11]
Vitamin K and potassium are essential micronutrients the body needs to develop and function properly. The two share some things in common, but they’re not the same.

Each has a unique set of properties and purposes. Unlike vitamin K, potassium is not a vitamin. Rather, it’s a mineral.

On the periodic table, the chemical symbol for potassium is the letter K. Thus, people sometimes confuse potassium with vitamin K.

This article highlights some of the main similarities and differences between vitamin K and potassium.

3. When two atoms bond together to form a molecule, which parts of the atoms
fenix001 [56]

Answer:

Atoms come together to form molecules because of their electrons. Electrons can join (or bond) atoms together in two main ways. When two atoms share electrons between them, they are locked together (bonded) by that sharing. These are called covalent bonds

What is the molar mass of aluminum (Al)
Papessa [141]

Answer:

26.981539 u

Explanation:

One mole of Al atoms has a mass in grams that is numerically equivalent to the atomic mass of aluminum. The periodic table shows that the atomic mass (rounded to two decimal points) of Al is 26.98, so 1 mol of Al atoms has a mass of 26.98 g.
