Question 4

How many moles of NaOH will be needed to neutralize 0.86 mol of H2SO4? The following equation is NON-balanced:

NaOH + H2SO4 --> Na2SO4 + H2O

Note: Use 2 decimal places (example, 0.56, 1.34) for your final answer.

Question 7

inHg is commonly used as unit of atmospheric pressure. It indicates the height of Hg (in inch) that atmospheric pressure can support. If atmospheric pressure is 27.2 inHg, what is it in atm? Use decimals (not scientific notation) and 3 sig figs for your final answer.

Given: 1 in = 2.54 cm = 25.4 mm; 1 atm = 760 mmHg

Explanation / Answer

4.
2NaOH + H2SO4 --> Na2SO4 + H2O

2 mol NaOH = 1 mol H2so4

No of mole of NaOH = ?

No of mol of H2so4 = 0.86 mol

? = 0.86*2 = 1.72 mol

7. 27.2 inch = 690.88 mm

p= 690.88 MMhg

pressure in atm = 0.91
