Question

ello guys ❤❤....calculate number of moles of hydrogen in 0.448 litre of hydrogen gas at STP.​

Answer 1

Answer:

HELLO MATE HERE IS YOUR ANSWER

Explanation:

For number of moles[n]

n=m/M

where,

m=given mass

M=molar mass

so given mass of hydrogen at stp=0=448

molecular mass of hydrogen [H2]=2

so n=m/m

=0.448/2

=0.224

by rounding off we can consider it as 0.25=1/4

so n=1/4mole
