Answer 1

Explanation:

carbon ioxide cde ok please mark

Answer 2

Answer:

Number of moles of sucrose =

Molarmass

Givenmass

=

342.3

25.6

=0.074 mol

Number of sucrose molecules in 1 mol = 6.022×10 ²³

No. of sucrose molecules in 0.074 mol = 6.022×10 ²³

×0.074=4.503×10²²

no. of hydrogen atoms in 1 molecule of sucrose = 22

Therefore, Number of hydrogen atoms in 4.503×10²²

22

molecules = 22×4.503×10²²

22

= 9.91×10 ²³
