Question

What is the mass of 1.0 x 10-3 mole of zn?

Answer 1

6.54x10^{-2}gZn

Step-by-step explanation:

Hello,

By applying the following mole-mass relationship, one could compute the mass of the given moles of Zn:

`m_(Zn)=1x10^(-3)molZn*(65.409gZn)/(1molZn) =6.54x10^(-2)gZn`

This is attained by considering that in 1 mol of Zn there are 65.409 g of Zn.

Best regards.

Answer 2

The amount of a substance can be converted into grams of that substance by using the molar mass. It is a physical property of a substance which describes the mass per mole of the substance. The molar mass of Zn is 65.38 g/ mol. Multiplying the given amount of Zn with the molar mass will yield to the mass of the substance.

1.0 x 10^-3 x 65.38 = 0.0654 g Zn
