Answer:
You need to add 3 100 pound bags of Parkerâs Premium Starter and 5 100 pound bags of Vigoro Ultra Turf fertilizer
Explanation:
You can obtain 3 equations. One for each compound:
For N:
177 pounds = 29x + 18y <em>(1) </em>
<em>-</em><em>Where x are bags of Vigoro Ultra Turf fertilizer</em><em> </em><em>and y are bags of </em>Parkerâs Premium Starte-
For P₂O₅:
134 pounds = 3x + 25y <em>(2)</em>
For K₂O:
42 pounds = 4x + 6y <em>(3)</em>
Replacing (1) in (2):
134 = (531/29 - 54y/29) + 25y
3355/29 = 671y/29
<em>y = 5 bags</em>
Thus,
<em>x = 3 bags</em>
You can replace in each equation to prove that this is the right result.
I hope it helps!

Answer:
The molarity of the solution is 245, 2M.
Explanation:
We calculate the molarity, which is a concentration measure that indicates the moles of solute (in this case KCl03) in 1000ml of solution (1 liter):
0,25 L solution----- 61,3 moles of KCl03
1 L solution----x= (1 L solution x 61,3 moles of KCl03)/0,25 L solution
x=245, 2 moles of KCl03 --> <em>The molarity of the solution is 245, 2M</em>
<em></em>
The molar mass is 294.1527 g/mol
Answer:
Dispersion forces
Relative molecular mass
Explanation:
Alkanes experience only dispersion forces. Dispersion forces increase with increasevin the relative molecular mass of the compounds. Hence a higher relative molecular mass implies greater dispersion forces and a greater boiling point.
