How many atoms are in 0.750 moles in zinc?

4.52 × 10^23 atoms

Concept being tested: Moles and Avogadro's number

From the question we are given;

We are required to calculate the number of atoms of Zinc

Therefore;

1 mole of Zinc = 6.022 × 10^23 atoms

To calculate the number of atoms we need to multiply the number of moles with the Avogadro's constant.

 = 0.750 moles × 6.022 × 10^23 atoms

= 4.52 × 10^23 atoms

Therefore; 0.750 moles of Zinc contains 4.52 × 10^23 atoms

hey your not cool]      

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
