Answer:

Step-by-step explanation:

Data:
n = 5 mol
V = 2.5 L
Calculation:

The molar concentration of the solution is
.
Answer: -
A) 3.59
Explanation: -
The number of significant figures in 2.06 = 3
The number of significant figures in 1.743 = 4
The number of significant figures in 1.00 = 3
During multiplication of significant figures, the number of significant figures in the answer would be the smallest value that is 3 in this case.
2.06 x 1.743 x 1.00 = 3.5908.
The answer to 3 significant figures is
2.06 x 1.743 x 1.00 = 3.59
Thus, Andi when performs the calculation that is shown below.
(2.06)(1.743)(1.00)
the answer be reported using the correct number of significant figures as A) 3.59

Answer:
1.5x10²² particulates
Explanation:
Assuming ideal behaviour, we can solve this problem by using the <em>PV=nRT </em>formula, where:
- V = 250 mL ⇒ 250 / 1000 = 0.250 L
- R = 0.082 atm·L·mol⁻¹·K⁻¹
- T = 15 °C ⇒ 15 + 273 = 288 K
We <u>input the given data</u>:
- 2.4 atm * 0.250 L = n * 0.082 atm·L·mol⁻¹·K⁻¹ * 288 K
And <u>solve for n</u>:
Finally we <u>calculate how many particulates are there in 0.025 moles</u>, using <em>Avogadro's number</em>:
- 0.025 mol * 6.023x10²³ particulates/mol = 1.5x10²² particulates
