1) The local weather states that the barometric pressure is 29.58
1) The local weather states that the barometric pressure is 29.58 in Hg convert this pressure to atm. (note 1 in=25.4 mm) I got 0.988 atm is that right?
2)A 7.32 L tire contains 0.448 mol of gas at a temperature of 28 C. What is the pressure(in atm) of the gas in the tire?
3)What is the pressure of an 8.5 L cylinder filled with 23.5 grams of nitrogen gas at a temperature of 298K?
4)Zinc reacts with hydrochloric acid to produce hydrogen gas as shown in the reaction below:
Zn(s)+2HCl (aq)-----> ZnCl2 (aq) + H2(g) The mass of zinc was 0.125 grams, the barometric pressure recorded was 758 mm Hg the temperature was 20 C. Assuming all the zinc reacted, find the volume of gas (H2) collected.
Please help I am so confused
