Answer:
Heyo (Ish Mash Potato) XD
Explanation:
a freighter carrying a cargo of uranium hexafluoride sank in the english channel in 1984. the cargo of uranium hexafluoride weighed 2.25x10 to the eight power. kg and was contained in 30 drums, each having a volume of 1.62x10 to the sixth power L. what is the density in g/ml, of uranium hexafloride.
Hope Mr. Mash Potato Helped!!!
The molarity is moles/liters.
First, convert 4,000 mL to L:
4000 mL --> 4 L
Now, you must convert the 17 g of solute to moles by dividing the number of grams by the molar mass. The molar mass of AgNO3 is <span>169.87 g/mol:
17 / 169.87 = .1
Now that you have both the number of moles and the liters, plug them into the initial equation of moles/liters:
.1/4 = .025</span>
True.
Because some people breathe less pollution and face lower risks of premature death and other serious health
Covalent bonds are strong bonds. Atoms that share pairs of electrons form molecules. A molecule is a group of atoms held together by covalent bonds. A diatomic molecule is a molecule containing only two atoms.
0.000132 g of hydrated sodium borate (Na₂B₄O₇ · 10 H₂O)
Explanation:
First we need to find the number of moles of sodium borate (Na₂B₄O₇) in the solution:
molar concentration = number of moles / volume (L)
number of moles = molar concentration × volume (L)
number of moles of Na₂B₄O₇ = 0.1 × 0.5 = 0.05 moles
We know now that we need 0.05 moles of hydrated sodium borate (Na₂B₄O₇ · 10 H₂O) to make the solution.
Now to find the mass of hydrated sodium borate we use the following formula:
number of moles = mass / molar weight
mass = number of moles × molar weight
mass of hydrated sodium borate = 0.05 / 381 = 0.000132 g
