Solute is substance which is dissolve in a solvent and Solvent is a substance that dissolves solute in a solution.
Answer:
The number of moles of AlBr3 = Molarity × Volume
= 0.400 × 0.700
= 0.28 moles
1 mole of AlBr3 gives 3 moles of Br- ions
That is
AlBr3 = Al3+ + 3Br-
Therefore, 0.045 moles of AlBr3 will yield 3 × 0.28 = 0.84 moles
Thus; they are 0.84 moles of bromide ions
The organs in the alimentary canal are important to digestion because they work together to move food and waste through the body. Without them, food wouldn't be able to move to their correct organs to digest and provide nutrients & energy, and waste would not be able to get out of the body.
Answer:
12.044 x 10^23 atoms Na
Explanation:
1 mol Na has 6.022 x 10^23 atoms of Na
2 moles Na have 2 x NA = 2 x 6.022 x10^23 atoms Na
