Question

calculate the no of particle in each of following 46 gm of sodium​

Answer 1

■---■---■---■

Sodium = Na

Atomic mass of Na = 23u

1 mole of Na =

$6.022 \times {10}^{23} atoms$

Number of moles in 46g of Na =

$\frac{46}{22} = 2 \: moles$

Number of moles in 46g of Na = 2 moles

$1 \: mole \: = 6.022 \times {10}^{23}$atoms

$2 \: mole \: = 6.022 \times {10}^{23} \times 2$

Number of particles jn 46g of Na =

$12.044 \times {10}^{23} \: atoms$
