A gas is at a pressure of 4.30 atm. what is this pressure in kilopascals? in mm hg?
Monica [59]
Units to measure pressure are as follows
atm - atmospheric pressure units
kPa - kilo Pascals
mm Hg - milimeters Hg
conversion units are;
 1 atm = 101 325 Pa
therefore 4.30 atm = 101 325 Pa / atm x 4.30 atm = 435.7 Pa

1 atm = 760.0 mm Hg
 4.30 atm = 760.0 mm Hg / atm x 4.30 atm = 3268 mm Hg

answers are 435.7 Pa and 3268 mm Hg

How many grams of water are produced when oxygen reacts with an excessive amount of propane (C3H8)?
lora16 [44]

Answer:

From the equation you will see that 1 mol of propane generates 4 mols of water.

Since the molar mass of water  

M ( H2O)=2×1+16=18g/mol

2 mol propane will generate  

2 ×4×18=144g   of water

Explanation:

Since the molar mass of water  

M ( H2O)=2×1+16=18g/mol

2 mol propane will generate  

2 ×4×18=144g   of water
