What is the mass in grams of 8.65 mol C8H18?

Chemistry
1 answer:
aliina [53]3 years ago

Answer:

m = 998 g

Explanation:

Hello there!

In this case, according to the definition of the molar mass as the mass of one mole of the compound, it is possible to state the 1 mole of C8H18 has a mass of 114.26 grams; therefore, the mass in 8.65 moles turn out to be:

m=8.65mol*\frac{114.26g}{1mol}\\\\m=998g

In agreement to the notation requirement.

Best regards!

Is water going from liquid to solid a physical or chemical change and why
Kipish [7]
It would be a physical change. It’s still water just in a different physical form. If it was a chemical change, it would no longer be water. For example, when the ice melts back into water...it’s still water.

What is the mass of 4.40 moles of magnesium chloride, MgCl2?
Darya [45]
Since the number of moles of a substance is the mass divided by the molar mass of the substance, we can just simply multiply the molar mass of magnesium chloride by the number of moles, which is 4.40 in this case.

To find the molar mass, refer to the periodic table for the relative atomic mass of Mg and Cl and add them together. Since there’s 2 chloride ions in MgCl2, double the relative atomic mass of Cl when adding.

24.31 + 35.45x2
=95.21

Now just multiply 95.21 to 4.40mol, which you’ll get 418.9g (corrected to 3 significant figures)
