Question

How many atomic mass units are there in 8.4 g?

Answer 1

a.m.u=5.1x10^{24}a.m.u

Step-by-step explanation:

Hello,

In this case, one one can use the equivalence for 1 g with the Avogadro's number to compute the atomic mass units as follows:

`a.m.u=8.4g*(6.022x10^(23)a.m.u)/(1g) \\a.m.u=5.1x10^(24)a.m.u`

Best regards.

Answer 2

The number of amu in 8.4 g = 5.1*10^24 amu

Step-by-step explanation:

Given:

Mass in grams = 8.4 g

To determine:

The equivalent in amu (atomic mass units)

Calculation:

Unit conversion-

1 g = 6.022*10^23 amu

therefore the given mass is equivalent to:

`(8.4g*6.022*10^(23)amu )/(1g) =5.1*10^(24) amu`
