Answer:
I think it's Element and compound
Explanation:
Answer:
The answer is 39.99711. We assume you are converting between grams NaOH and mole. You can view more details on each measurement unit: molecular weight of NaOH or mol This compound is also known as Sodium Hydroxide. The SI base unit for amount of substance is the mole.
I don't know what the options were but a material that is very likely going to be challenging to recognize under a microscope as a mixture is a homogeneous mixture. A homogenous mixture is uniform and thus hard to recognize as a mixture. An example is water!
Answer:
Moles of air 0.1245 mol.
Explanation:
Given data:
Pressure = 1 atm
Temperature = 293 K
Volume = 3 L
Number of moles = ?
Solution:
PV = nRT
R = general gas constant = 0.0821 dm³ atm . K⁻¹ . mol⁻¹
Now we will put the values in equation
PV = nRT
n = PV / RT
n = 1 atm . 3 L / 0.0821 dm³ atm . K⁻¹ . mol⁻¹ . 293 K
n = 3 / 24.1 dm³ atm. mol⁻¹
n = 0.1245 mol
