Explanation:
It is 292.5 m because you do 4.5 hours times 65. (please give me brainliest)
Answer:
Molar mass of monoprotic acid is 1145g/mol.
Explanation:
The reaction of a monoprotic acid (HX) with NaOH is:
HX + NaOH → H₂O + NaX
That means 1 mole of acid reacts with 1 mole of NaOH
If the neutralization of the acid spent 20.27mL of a 0.1578 M NaOH solution. Moles of NaOH are:
0.02027L × (0.1578mol / L) = <em>3.199x10⁻³ moles</em> NaOH ≡ moles HX.
As mass of the sample is 3.664g, molar mass of the acid is:
3.664g / 3.199x10⁻³ moles =<em> 1145g/mol</em>
Answer:
<h2>The answer is 2.52 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass of object = 15.9 g
volume = final volume of water - initial volume of water
volume = 56.3 - 50 = 6.3 mL
It's density is
We have the final answer as
<h3>2.52 g/mL</h3>
Hope this helps you
Answer: NaCl and LiNO3
Explanation:
Because in aqueous solution they ionize
NaCl produces Na+ and Cl-
And LiNO3 produces Li+ and NO3- ion
