Answer:
2059.645g Cl
Explanation:
A mole of any element contains 6.022e23 molecules, so we will divide the given amount of molecules by 6.022e23.
3.5e25 / 6.022e23 = 5.81e1
5.81e1 = 58.1 mol Cl
Now that we have found the amount of moles of Chlorine, we will multiply the number of moles by the molar mass of Chlorine, which is 35.45g/mol.
35.45(58.1) = 2059.645g Cl
Answer:
3.
Explanation:
- Al(OH)₃ reacts with HCl to produce AlCl₃ and water according to the balanced equation:
<em>Al(OH)₃ + 3 HCl → AlCl₃ + 3H₂O,</em>
<em></em>
<em>It is clear that 1.0 mole of Al(OH)₃ reacts with 3.0 mole of HCl to produce 1.0 mole of AlCl₃ and 3.0 moles of H₂O,</em>
<em />
<em>So, the coefficient of HCl is 3.</em>
<em></em>
It will approximately take 2 hours and 50 minutes
Answer:
As specific gravity is defined as weight per unit volume,so urine is the less dense fluid,so urine will be in hyperosmotic category.
