Question

a certain mass of gas is at a pressure of 1600 mm of Mercury. when the pressure is increased by 400 mm, it occupies a volume of 5800 cc at constant temperature what is the initial volume

pls help me ​

Answer 1

Answer:

31. 4.4 g of an unknown gas occupies 2.24 litres of volume at STP. The gas may be (1 carbon dioxide 2) carbon monoxide (3) oxygen (4) sulphur dioxide

Answer 2

Initial Volume of gas is 7250 cc.

Step by step explanation:

• Given data;

Initial pressure (P1) = 1600 mm of Hg

Final pressure (P2) is increased by 400 mm of Hg that means our

P2 = 2000 mm of Hg

Final Volume (V2) = 5800 cc

• Formula used;

We used here the formula of Boyle's law which is,

P1 × V1 = P2 × V2

• Calculation of V1;

By rearranging above formula ,

V2 = $\frac{V2 * P2}{P1}$

we have all the required values , by putting them we get ,

V2 = $\frac{5800 * 2000}{1600}$ = 7250 cc

Initial volume of gas = 7250 cc.
