Which of the following would have the greatest mass?

15.0 moles of N
20.0 moles of H
5.0 moles of Zn
1.0 moles of Pb

5.0 moles of Zn.

Explanation:

From the molar masses we get 15 moles of N  =  15* 14 =   210 g.

20 moles of H = 20.16 g,

5 moles of Zn = 5*65.38 = 326.9 g.

1 mole of lead = 207.2 g.

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.
