6.02
x 1023 . Identify the correct
statement.
A) there are 6.02 x 1023atoms in 0.5mol of
neon gas
B) there are 6.02 x 1023 electrons in 0.5
mol of hydrogen gas.
C) there are 6.02 x 1023 molecules in 0.5
mol oxygen gas
D) there are 3.01 x 1023 hydrogen atoms
in 0.5 mol water​

Answer 1

Answer:

OPTION (D)

Explanation:

$3.01 \times {10}^{23} \: \: hydrogen \: \: atoms \: \: in \: \: 0.5 \: mole \: of \: \: water$

Answer 2

Answer:

the answer is option b because in 1 mole of H2 gas there are 2moles H atoms. so in 0.5 mole there will be 1 moleH atoms. 1 H atom has 1 electron therefore and 1 mole H atoms has 1 mole electrons
