Question

a gas of mass 32g has a volyme of 20 litres at stp. calculate the gram molecular weight of the gas​

Answer 1

Answer:

351g aprox

Explanation:

Moles=volume/22.4

moles=20/22.4

moles =mass/gram molar mass

20/22.4=32/gmm

gmm=32*11.2/10

gmm=35.84g

as it is mass , weight =mass * gravity

therefore weight=35.84*9.8

weight is 351.23 g

please make me brainliest

Answer 2

Answer:

35.84 gm

Explanation:

Given, 20 litres of gas at STP = 32 gm

Thus, 22.4 litres of gas will be=(32×22.4) / 20 g

= 3584/100 gm

= 35.84 gm

This is the answer.
