Answer:
2.566
Step-by-step explanation:
The molar weight of Na is 22.989769 g, so 59 g represents ...
(59 g)/(22.989769 g/mol) = 2.566 mol
2.566 mol of Na will react to produce 2.566 moles of NaCl when Cl is available in excess.
Answer:
204
Step-by-step explanation:
A quotient is a result of division.
1836 ÷ 9 = 204
Answer:
7
Explanation:
There is a theorem that states that: "In any triangle, the sum of any two sides MUST be greater that the third side."
This means that, in the given triangle:
x + 2x > 18
3x > 18
x > 18/3
x > 6
Since x should be greater than 6 for the dimensions to be valid, therefore, the smallest possible integer for x is the one directly after the 6 which is 7.
Hope this helps :)
