to counteract the sourness of the acids. just did this assignment so i know this is correct
Answer:
compound
Explanation:
MgO is an inorganic compund :) The simplest explanation is that it's not an element b/c there's two elements (Mg & O) in the substance, and it's not a mixture b/c you can't easily separate the two elements.
Here, we need to solve this problem using Ideal gas law ( PV=nRT).
Where –
- P = Pressure in atm
- V = Volume in L
- n = moles
- R = Ideal gas law constant
- T = Temperature in K
<u>Now, according to the question </u>–
- V = 58 L
- P = 2.2 atm
- T = 313 K
- R = 0.0821 atm L/ mol K
<u>Calculation</u> –

Answer:
The answer to your question is 0.10 M
Explanation:
Data
Molarity = ?
mass of Sucrose = 125 g
volume = 3.5 l
Formula
Molarity = moles / volume
Process
1.- Calculate the molar mass of sucrose
C₁₂H₂₂O₁₁ = (12 x 12) + (1 x 22) + (16 x 11)
= 144 + 22 + 176
= 342 g
2.- Convert the mass of sucrose to moles
342 g of sucrose ------------------- 1 mol
125 g of sucrose -------------------- x
x = (125 x 1) / 342
x = 0.365 moles
3.- Calculate the molarity
Molarity = 0.365 / 3.5
4.- Result
Molarity = 0.10
