Question

Q: calculate the number of particles in 6.9g of znso4.​

Answer 1

Explanation:

molar mass of Znso4 = 145g

145g of Znso4 has

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

:: 6.9g of Znso4 has 6.022×10^-23/6.9 × 145

Answer 2

Answer:

molar mass of Znso4 = 145g

145g of Znso4 has

6.022 \times 10 { e }^{23}6.022×10e

23

:: 6.9g of Znso4 has 6.022×10^-23/6.9 × 145...
