Answer:
Explanation:
We will need a balanced chemical equation with masses and molar masses, so, let's gather all the information in one place.
MM: 142.04 233.29
Ba²⁺ + Na₂SO₄ ⟶ BaSO₄ + 2Na⁺
m/g: 27.4
(a) Moles of Na₂SO₄
(b) Moles of BaSO₄
(c) Mass of BaSO₄
How does protein help with wound healing? Your body needs protein to help build and repair muscle, skin, and other body tissues. Protein also helps fight infection, balance body fluids, and carry oxygen through your body. When you have a wound that's healing, think of food as medicine.
Answer:
The final molarity of nitrate anion in the solution is 0.258 M.
Explanation:
Mass of barium nitrate 1.73 g
Moles of barium nitrate =
1 mole of barium nitrate gives 2 moles of nitrate ions,then 0.00662 mol of barium nitrate will give :
of nitrate ions
moles of nitrate ion added to the solution = 0.01324 mol
Molarity of the barium nitrate solution = 63.0 mM = 0.063 M
1 mM = 0.001 M
Volume of barium nitrate solution = 100 mL = 0.100 L
1 m L = 0.001 mL
Moles of barium nitrate in the solution = n
Moles of nitrate ion in solution = 2 0.0063 × mol = 0.0126 mol
Total moles og nitrate ions = 0.01324 mol + 0.0126 mol = 0.02584 mol
Final molarity of nitrate anion in the solution.:
The final molarity of nitrate anion in the solution is 0.258 M.

The average atomic mass of uranium = 313.826 amu
What is average atomic mass ?
The weighted average mass of the atoms in a naturally occurring sample of an element is the average atomic mass, also known as atomic weight. Unified atomic mass units (u), where 1 u is equal to precisely one-twelfth the mass of a neutral atom of carbon-12, are the standard units used to express average masses.
average atomic mass =
