Because 1 atm is equal to 760mm Hg, you can use the following equation to find the correct atm measurement:
atm x 760
Simply plug the values given in:
0.43 x 760 = 326.8mm Hg

Answer:
33.3
Explanation:
if we were to add 29.0 of argon and 4.30 of sulfur and that would come out 33.3.
Explanation:
There are ten d electrons in the outermost d subshell for Zn2+.
Gasoline and motor oil are chemically similar. They are both mixtures of nonpolar hydrocarbons containing carbon and hydrogen atoms. However, motor oil is much more viscous Motor Oil

Water’s molar mass is 18.01 g/mol. The molar mass of methanol is 32.01 g/mol. At room temperature, water is 64% more viscous than methanol. Which substance has the stronger intermolecular attraction? water
Answer:
- Acid-Base reaction (the reactanct acting as a base is NaOH)
Explanation:
The reaction that takes place is:
- C₃H₅O(CO₂H)₃(aq) + 3OH⁻ (aq) → C₃H₅O(CO₂)₃⁻³(aq) + 3H₂O(l)
This is a <em>acid-base reaction</em>, with the citric acid acting as the acid and the <u>sodium hydroxide NaOH acting as the base.</u>
We <u>calculate the moles of citric acid</u> using the information from the titration:
- 0.0142 L * 0.340 M *
= 1.609x10⁻³ mol citric acid
Now we <u>convert moles to mass</u> using the acid's molecular weight (192.13g/mol):
- 1.609x10⁻³ mol citric acid * 192.13g/mol = 0.3092 g citric acid
Finally we calculate the mass percent of citric acid in the sample:
- 0.3092 g / 16.00 g * 100% = 1.93%
