Question

A flask can hold 1.75 g of hydrogen.The same flask can hold 40.25 g of gas P under similar conditions of temperature and pressure.Calculate the relative molecular mass of gas P.​

Answer 1

Answer:

23 g relative to hydrogen 1g.

Explanation:

lets say volume is V of the flask.

volume of 1g of hydrogen ar STP is 1/1*22.4 = 22.4L

so total volume V is 1.75*22.4 = 39.19L

lets say P has Molar mass of M.

mile of p is 40.25/M.

volume = (40.25/M)*22.4 = 1.75*22.4

SOLVING FOR M = 40.25/1.75 = 23

so answer is 23

Answer 2

Answer:

Explanation:lets say volume is V of the flask.

volume of 1g of hydrogen ar STP is 1/1*22.4 = 22.4L

so total volume V is 1.75*22.4 = 39.19L

lets say P has Molar mass of M.

mile of p is 40.25/M.

volume = (40.25/M)*22.4 = 1.75*22.4

SOLVING FOR M = 40.25/1.75 = 23
