How many g of nacl do need to make 1.00L of 2.5% w/v solution of nacl in water?
iren2701 [21]
2.5 % w/v ( that means we have 2.5 grams of solute in 100 mL <span>solution )

1.00 mL = 1000 mL therefore:

2.5 g ------------- 100 mL
?? --------------- 1000 mL

1000 x 2.5 / 100 => 25.0 g of NaCl</span>

A gaseous air‑fuel mixture in a sealed car engine cylinder has an initial volume of 600.mL at 1.0atm. To prepare for ignition of
Ket [755]

12 atm is the new pressure of the air‑fuel mixture when A gaseous air‑fuel mixture in a sealed car engine cylinder has an initial volume of 600 ml at 1.0atm and final volume of 50 ml.

Explanation:

Data given:

The air fuel mixture is assumed to be having ideal behaviour

initial volume of gaseous air fuel mixture V1 = 600 ml

initial pressure of gaseous air fuel mixture P1= 1 atm

final volume when piston is removed, V2= 50 ml

final pressure of the gaseous air mixture, P2 = ?

Applying the Boyle's Law,

P1V1 = P2V2

rearranging the equation:

P2 = \frac{P1V1}{V2}

putting the value in the equation,

P2 = \frac{600 X 1}{50}

P2 = 12 atm

the pressure is increased to 12 atm when volume is reduced to 50 ml.
