A tire has a pressure of 3.26atm. Calculate this pressure in kilopascals

The answer to your question is 330.32 kPa

Explanation:

Data

Pressure = P = 3.26 atm

Pressure in kPa = ?

Process

To solve this problem use proportions and cross multiplication. Look for the equivalence of atm to kPa.

                1 atm 101.325 kPa

          3.26 atm  x

                 x = (3.26 x 101.325) / 1

-Simplification

                 x = 330.32/ 1

-Result

                 x = 330.32 kPa

how to make a simple air condition

given:

mass of na = 115 g

excess cl2

to determine:

mass of nacl produced

explanation:

given reaction is-

2na(s) + cl2(g) → 2nacl(s)

since cl2 is in excess, na will be the limiting reagent

as per the reaction stoichiometry na: nacl = 1: 1

i.e. moles of na reacted = moles of nacl formed

now, # moles of na = mass of na/atomic mass

                                  = 115 g/23 g.mol-1 = 5 moles

therefore, moles of nacl = 5

molar mass of nacl = 58 g/mol

mass of nacl = 5 moles * 58 g.mol-1 = 290 g

ans: amount of nacl produced = 290 g
