Answer:
1.75moles
Explanation:
Molarity = number of moles (n) ÷ volume (V)
According to the information given in this question,
V = 500mL = 500/1000 = 0.500L
n = ?
Molarity = 3.5M
Using Molarity = n/V
number of moles (n) = V × molarity
n = 0.5 × 3.5
n = 1.75moles.
Answer:
the result for the following are (a) P is directly proportional to n
(b) V is directly proportional to T (c) P is directly proportional to T (d) T is inversly proportional to V (e) P is inversely proportional to V
Answer:
I think it would be 9 moles.
Scientific notation is: n * 10^a, where n is a number between 1 and 10 ( but not 10 itself ) and a is an integer.
We move decimal place to the left to create a new number from 1 to 10.
Answer:
0.0000250 m = 2.5 * 10^(-5) m.
