Question

7. Calculate how much volume of 8g. Hydrogen gas occupies at STP. ​

Answer 1

Answer:

Hope it helped you

Explanation:

Fortunately, Count Amadeo Carlo Avogadro (1776 – 1856) provided us with Avogadro’s Number, which is the number of molecules contained in 1mol of a substance at STP.

This number is 6.022x10^23.

Furthermore, 1mol of a gas at STP occupies 22.4L

In this case, we have 8g of hydrogen at STP, which is 8g/2g/mol = 4mol

So, at STP, 4mol of hydrogen occupies 4x22.4 = 89.6L

Answer 2

Explanation:

we know that 2g of hydrogen occupied 22.4l at STP

So,

1g occupies = 22.4/2=11.2l

so,

8g occupies =8 multiplies 11.2

=89.6 l
